Inserting data to mysql table using php

Tjobbe · #1 (**permalink**) 09-28-06, 06:54 AM

Right, a simple one, but I can't for the life of me figure it out, I've looked at a few dozen tutorials and code snippets but for some reason the data I want to enter will not display as I want it to.

Basically, I have a file with two fields, title and content, on submitting the form it goes to insert.php which "should" add the data to the table, but it does not.

I'd like the id to increase each time an entry is added and for the date to be autosubmitted too, is this possible?

The files are below, if anyone could point out the obvious then I'd be most grateful!

index.php

PHP Code:


			
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">

<HTML>

<HEAD>

<TITLE> New Document </TITLE>

<META NAME="Generator" CONTENT="EditPlus">

<META NAME="Author" CONTENT="">

<META NAME="Keywords" CONTENT="">

<META NAME="Description" CONTENT="">

</HEAD>



<BODY>

<form action="insert.php" method="post">

    Title: <input type="text" name="title" /><br />

    Content: <input type="text" name="content" /><br />

    <input type="submit" />

</form>

</BODY>

</HTML>

insert.php

PHP Code:


			
<?



include "dbconnect.php";



$title="$_POST['$title]";

$content="$_POST['$Scontent]";



$sqlquery = "INSERT INTO entries VALUES('$title','$content')";



$results = mysql_query($sqlquery);



print "<html><body><center>";

print "<p>You have just entered this record<p>";

print "title : $title<br>";

print "content : $content<br>";

print "</body></html>";



?>

dbconnect.php

PHP Code:


			
<?php



$dbhost = 'localhost';

$dbuser = 'root';

$dbpass = 'inflight';



$conn = mysql_connect($dbhost, $dbuser, $dbpass)

or die('Error connecting to mysql');



$dbname = 'testing';

mysql_select_db($dbname);



?>

my table, the entries in there are what i added manually through phpmyadmin:

i think your problem is here:

PHP Code:


			
$title="$_POST['$title]";

$content="$_POST['$Scontent]";

you don't have to parse them as strings, as they are allready strings. Bu this s not causing the problem. You have a dollar sign before "Scontent" and "title", i think this has to be removed. this is what should be there:

PHP Code:


			
$title=$_POST['title'];

$content=$_POST['Scontent'];

also add 'or die(mysql_error());' after every mysql_query(), that way you can check what mysql returns as error.

I'm sure the error must be coming from the insert.php page, I've ammended the code a little:

PHP Code:


			
<?



include "dbconnect.php";



$sqlquery = "INSERT INTO entries VALUES('id','title','content','date')";



$results = mysql_query($sqlquery) or die(mysql_error());



print "<html><body><center>";

print "<p>You have just entered this record<p>";

print "title : $title<br>";

print "content : $content<br>";

print "</body></html>";



?>

I now get the following error on submitting the form: "Out of range value adjusted for column 'id' at row 1"

What does that mean? is the id and date fields not auto inserting? i know im not passing them, but ddont they get added automatically?

you're insert query is wrong:
it should be:

PHP Code:


			
$query = "INSERT INTO entries ('id', 'title', 'content', 'date') VALUES('', 'my_title', 'my_content', 'my_date')";

// or:

$query = "INSERT INTO entries VALUES('', 'my_title', 'my_content', 'my_date')";

// or:

$query = "INSERT INTO entries SET title='my_title', content='my_content', date='my_date'";

the reason why you got this error is because you were assigning a string to an integer type: id was an int(4) NOT NULL auto_increment, not a string

just this second fixed it, thanks for replying!

PHP Code:


			
<?



include "dbconnect.php";



$title=$_POST['title'];

$content=$_POST['content'];



$sqlquery = "INSERT INTO entries VALUES(id,'$title','$content',NOW())";



$results = mysql_query($sqlquery) or die(mysql_error());



print "<html><body><center>";

print "<p>You have just entered this record<p>";

print "title : $title<br>";

print "content : $content<br>";

print "</body></html>";
