Hello php coders,

I am creating a form that uses images instead of buttons to submit information and I found some problems: type=image does not pass the value.

I am creating this system to delete lines from a shopping cart, therefore every "delete" button has a different value but I am not able to get it once the form is processed.

Exmaple:

<table>
<form name="formulario" action="pruebas.php" method="post">
<tr>
<td>
<input name="delete" type="IMAGE" value="7" src="a.gif" width="70" height="26" border="0">
</td>
</tr>
</form>
</table>

once this form is submitted I echo $delete and nothing appears on the screen, I could use $delete_x and get the some screen coordinates.

I got a workaraound but it looks a little complex:

I inserted the value of the button inside the name tag like

name="delete_id"

while (list ($clave, $val) = each ($HTTP_POST_VARS)) {
if (ereg("x", $clave) > 0){
$clave2_array = explode("_", $clave);
$clave2 = $clave2_array[1];
echo "The value is" . $clave2 . " and the button is" . $clave2_array[0];;
} // if
} //while


this way I get the value passed.

This problem only happens on IE, Mozilla treats the type=image as a type=submit.

Did you find any other solution to this?

Thanks

what about using a hidden input with the id as value.... and just never look at the button

[Pepe]

this way... which of the delete buttons in associated to which hidden input? say you have three items in your shopping cart and want to delete id_cart="7".... hope you understand this.

Take a look at what Amazon is doing:

<input type=image name="submit.delete-id.U168FU" value="Delete" border=0 alt="Delete" src=http://g-images.amazon.com/images/G/01/detail/delete-sm-01.gif width=44 height=14 >

You could have a hidden input with the value of the row to be deleted, and when the user clicks on the 'delete' button it uses 'onMouseDown' to set the hidden inputs value then submits the form.

this means javascript is enabled on the browser, I want my shopping cart JS FREE.

Thanks

You could also have seperate forms for each item and have the action something like './delete.php?id=2'.

good idea, I will go on with this option.

Thank you all.

this was actually what I had in mind while writing my post, though I was thinking of a seperate form per item. this solution though, is much more efficient in html coding. less forms == good
