samara · #1 (**permalink**) 06-04-09, 09:08 PM

Hello Sir,

This is my Task!!
When ever user comment and clicks add, i need to open an HTML file from a directory(i need to open an existing file which i know), i need to locate a string </head> and i need to put the value of the text field there like this:

Comment is the name of the text field the user has to enter into to enter the text into the file!!

<meta name="comment" content="value in the text field ie ($_REQUEST['comment']">

now i have this
if($_REQUEST['comment'])
{
$file_contents = file_get_contents(REPORTS_DIR."/$FILENAME");

$find_string = '</head>';

now how to add the new string <meta name="comment" content="value in the text field ie ($_REQUEST['comment']"> above the </head>

Any help would be greatly appreciated!! If you need anyomore info, i can explain you in detail

Thanks!!

Thanks a lot for your reply sir, it was very helpful!!

My Next step is:
Now user has enetered the comment and he posted, its going into the file:

Now the files meta Tag is like this:
<meta name="comment" content="This is the first">

If user enters a new comment(this is the second comment), it should append to the first comment in a new line like this:

<meta name="comment" content="This is the first
This is the second comment">

Any help please

Code:

function addMetaTag($file, $separator, $metaTag)
{
 $file_contents = file_get_contents($file);
 $file_parts = explode($separator, $file_contents);
 $newFile = $file_parts[0].$metaTag.$separator.$file_parts[1];
 file_put_contents($file, $newFile, LOCK_EX);
 }

if(isset($_REQUEST['comment']) && $_REQUEST['comment'])
{
 $file = REPORTS_DIR."/$FILENAME";
 $separator = "</head>";
 $metaTag = "<meta name=\"comment\" content=\"".$_REQUEST['comment']."\">\r\n";
 addMetaTag($file, $separator, $metaTag);
 }

// See the results. //
//echo "<span style='font-size:24px;font-weight:bold;'><u>New file</u> :</span><br />".nl2br(htmlspecialchars(file_get_contents($file)));

  print "<html>";
  print "<form method='POST'>";
  print "<div class='normal_header'>Comment:</div><textarea name = 'comment' id = 'txtarea1' rows = '3' cols = '30' ></textarea/></br><input type='submit' name='submit' value='Post' />";
  print "</form>";
  print "</html>";

Thanks a lot for your reply, but you have totally changed everything, this is of no help for me,

i was not even able to understand which function is actually appending to the existing content, the $metatag name is so confusing!!

This is my code now!!

Code:

function addMetaTag($file, $separator, $metaTag)
{
 $file_contents = file_get_contents($file);
 $file_parts = explode($separator, $file_contents);
 $newFile = $file_parts[0].$metaTag.$separator.$file_parts[1];
 file_put_contents($file, $newFile, LOCK_EX);
 }

if(isset($_REQUEST['comment']) && $_REQUEST['comment'])
{
 $file = REPORTS_DIR."/$FILENAME";
 $separator = "</head>";
 $metaTag = "<meta name=\"comment\" content=\"".$_REQUEST['comment']."\">\r\n";
 addMetaTag($file, $separator, $metaTag);
 }

// See the results. //
//echo "<span style='font-size:24px;font-weight:bold;'><u>New file</u> :</span><br />".nl2br(htmlspecialchars(file_get_contents($file)));

  print "<html>";
  print "<form method='POST'>";
  print "<div class='normal_header'>Comment:</div><textarea name = 'comment' id = 'txtarea1' rows = '3' cols = '30' ></textarea/></br><input type='submit' name='submit' value='Post' />";
  print "</form>";
  print "</html>";

Now my task is!! when ever the page loads:

If the metatag comment is not present in the file or this is the first time user is entering a comment, then there should not be any value in the text area, it should be blank.
so when now user enters something then the metatag is created, this is working fine for me!!

suppose
if there is a meta tag present already in the file, user has already entered a comment just before or long back, the value of the comment ie the content in the metatag should be displayed at the intial value of the text box.

<meta name="comment" content="This is the first">

so in this case when page loads, the value in the text area should be This is the first comment and just a post button.

for this i have written a metatag parser:

Code:

$file_contents = file_get_contents(REPORTS_DIR."/$FILENAME");

        //detect encoding
        if(!mb_detect_encoding($file_contents)) {
            //If encoding cannot be detected, assume UTF-16 and convert to UTF-8
            $CONV_TEXT = @iconv("UTF-16", "UTF-8", $file_contents);

            //Replace UTF-16 encoding parameter in report header with UTF-8
            $find_string = '<META http-equiv="Content-Type" content="text/html; charset=UTF-16">';
            $replace_string = '<META http-equiv="Content-Type" content="text/html; charset=UTF-8">';

            $TEXT = str_replace($find_string, $replace_string, $CONV_TEXT);
        }
        else {
            $TEXT = $file_contents;
        }



function parse_metadata($TEXT)
    {
        //grab data from each metatag
        $metadata = array();
        if ($TEXT)
        {
            if(preg_match_all('/<meta\s*name\s*=\s*"(.*)"\s*content\s*=\s*"(.*)".*>/Uim', $TEXT, $matches))
            {
                for($i = 0; $i < count($matches[1]); $i++)
                    $metadata[$matches[1][$i]] = $matches[2][$i]; // as far as i know here, when the function parses the metatag <meta name="" content="This is the first comment">,  ie $metadata['comment'] = This is the first comment
            }
        }
       
        return $metadata;
    }

if(isset($metadata['comment']))
{
now i want the value of $metadata['commen't] to be stored as the value of text area, this happens when page loads first and when the metatag is present already, but i am confused when to call this if(isset($metadata['comment'])) and how to assign this php variable value to textarea value!!
}

so now textarea has the initial value as the content or previous user entered comment or by default the textarea shows the comments that are present for the reports.

Now if user adds a new comment, it should append to the existing comment and should display whole updated comment (content value from metatag) in the textarea!!

i think i have pretty much done with it, but confused in calling the functions. i need your help.

If you haven't understood please lemme know. I will try to xplain further.

Just a brief summary.:

$metadata['comment']) is having the value of the comment that is present in the file.

$_REQUEST['comment'] is having the value of the text area after user addas and before clicking the post button

As of now, my first task would be completed if i was able to implement, showing the value of metatag content in the textarea as soon as page displays!!

If you just want to get the meta data from $metadata['comment'], then this will work.

PHP Code:


			
<?php
//detect encoding
function convert_encoding($file,$file_contents)
{
 $CONV_TEXT = @iconv("UTF-16", "UTF-8", $file_contents);   //If encoding cannot be detected, assume UTF-16 and convert to UTF-8
 $find_string = '<META http-equiv="Content-Type" content="text/html; charset=UTF-16">';     //Replace UTF-16 encoding parameter in report header with UTF-8
 $replace_string = '<META http-equiv="Content-Type" content="text/html; charset=UTF-8">';
 return str_replace($find_string, $replace_string, $CONV_TEXT);
 }

function parse_metadata($file)
{
 $file_contents = @file_get_contents($file);
 $TEXT = mb_detect_encoding($file_contents) ? $file_contents : convert_encoding($file,$file_contents);
 //grab data from each metatag
 $metadata = array();
 if($TEXT)
 {
  if(preg_match_all('/<[\s]*meta[\s]*name="?' . '([^>"]*)"?[\s]*' . 'content="?([^>"]*)"?[\s]*[\/]?[\s]*>/si', $TEXT, $matches, PREG_SET_ORDER))
  {
   for($i=0;$i<count($matches[0]);$i++){$metadata[$matches[$i][1]] = $matches[$i][2];}
   }
  }
 return $metadata;
 }

function no_metadata()
{
 GLOBAL $weight;
 // Set formatting for error message
 $weight = "font-weight:bold;font-size:16px;color:#f00;padding:10px;";
 return array('comment' => "Alert!!!\r\nNo metadata available.");
 }
 
// Initialize error formatting variable
$weight = "";

// Get the metadata and display it in a textarea element
$metadata = parse_metadata(REPORTS_DIR."/$FILENAME") ? parse_metadata(REPORTS_DIR."/$FILENAME") : no_metadata();
echo "<html>
      <head>
      <title></title>
      </head>
      <body>
       <form method='POST'>
        <div class='normal_header'>Comment:</div>
        <textarea name = 'comment' id = 'txtarea1' rows = '3' cols = '30' style='".$weight."'>"
         .$metadata['comment'].
       "</textarea/>
        </br>
        <input type='submit' name='submit' value='Post' />
       </form>
       </body>
       </html>";
?>

This code was really helpful!!
i added up a little extra!!

Now my code looks like this!!
Actually, everything works fine now, the only problem is (I have noted this line in the code below as " --------------->> This is where i am talking about"):

When user adds a second comment, a new meta tag is getting created, but i want the new comment to get appended to the existing one. I know you gave it in your last code, but the tagname confuses me a lot and i was not able to see how you are appending to the existing comment. I tried making chnages according to my situation but its making my result worse.

Right now, lets take an example:
User enters 3 comments at different times namely: hai how are you i am fine great its working good

after executing for all these different times, now the file looks like this:
<meta name="comment" content="hai how are you">
<meta name="comment" content="hai how are you
i am fine">
<meta name="comment" content="hai how are you
i am fine
great its working good">
[CODE]<?php
function addMetaTag($file, $separator, $metaTag)

But i want these three different comemnts to create only one metatag:
<meta name="comment" content="hai how are you
i am fine
great its working good">, just update the existing one, it sould not craete a new one.

Any help please, can you help me by adding changes to exisitng code, if i do this, my task will be done!!

Code:

<?php
function addMetaTag($file, $separator, $metaTag)
{
 $file_contents = file_get_contents($file);
 $file_parts = explode($separator, $file_contents);
 $newFile = $file_parts[0].$metaTag.$separator.$file_parts[1];
 file_put_contents($file, $newFile, LOCK_EX); 
 }

if(isset($_REQUEST['comment']) && $_REQUEST['comment'])
{
 $metadata = array();
 $file = REPORTS_DIR."/$FILENAME";
 $file_contents = file_get_contents($file);
 $separator = "</head>";

        if ($file_contents)
        {
            if(preg_match_all('/<meta\s*name\s*=\s*"(.*)"\s*content\s*=\s*"(.*)".*>/Uims', $file_contents, $matches))
            {
                for($i = 0; $i < count($matches[1]); $i++)
                    $metadata[$matches[1][$i]] = $matches[2][$i];

Thanks a lot for your help sir, i was able to do it!!

$find_string = $metadata['comment'];
$replace_string = $metadata['comment']."\n".$_REQUEST['comment'];
//echo $replace_string;
$holdcontents2 = str_replace($find_string, $replace_string, $file_contents);
//echo $file_contents;
file_put_contents($file, $holdcontents2);

Now my task is done!!

I need another help: In the same file on which i have been working, where i have updated the comments until now i have to pus the same comments in another place!!

I am aware of doing this: But the place where i have to enter is a string that looks like this:

Code:

<span style="color:#0000FF; font-family:Arial; font-size:10pt; font-weight:bold; ">Date/Time: </span><span style="font-family:Arial; font-size:10pt; font-weight:bold; ">Date05-27-2009-Time15-13-31</span><br>

this is the only distinct way i can search for the place: i have to insert the comments exactly after </span><br> at the end.

I have to open file, search through the text for Date/Time and walk through the text until i reach the first </span><br>.

And then insert the comment may be by putting a strpos there or something like that etc.

Can you please help me on this!!

the comment might look like this:

Code:

<span style="color:#0000FF; font-family:Arial; font-size:10pt; font-weight:bold; ">Comment: </span><span style="font-family:Arial; font-size:10pt; font-weight:bold; ">$metadata['comment'] [or] $replace_string</span><br>

if you have some other suggestions or ways of doing it, lemme knw!!

Thanks!!

The place marked as ------------------>> at this function:
i want echo $DisplayReport; to be run whenever te new comment is posted, everything works fine now: I want to refresh the page when ever the addcommentintohtml() function gets executed.

I tried so many online resources nothing is of no help, you can also give your own suggestion may be like php refresh function etc

Thanks!!

I sthere anyway i can do that, i dont want to refresh page after every n seconds, i want it to refresh only when comment is added or addcommentintohtml() is executed

Code:

function addMetaTag($file, $separator, $metaTag)

 file_put_contents($file, $newFile, LOCK_EX); 
}

function addcommentintohtml($replace_string, $FILENAME)

 $file1 = REPORTS_DIR."/$FILENAME";
 $file_contents = file_get_contents($file1);

Well, I am glad you figured it out.
But I am going to be very blunt with you.
I see you didn't learn very much.
You have a lot of redundancy in you code.
Why are you getting the contents of the file three times?
Why don't you get the contents of the file once in the beginning of the program and get it over with?

You need to rethink your logic and rewrite your code so it makes logical sense.
Then and only then, will you be able to see a way, how to do what you want.

I am not going to keep rewriting your code all the time unless you are willing to compensate me for my time.
But I think sense you should be learning something you should try and figure it out yourself, otherwise I charge $40 per hour for my time.
