form field not working

[pouncer]

[code]
<form method ='post' action='myprivatemessages.php' name='record'>
<td><input name='Submit' type=\"image\" src=\"../index_images/delete.ico\" ></td>
<input type='hidden' name='message_id' value='$message_id'>
</form>
[/code]

and then below i have:

[code]
  if (isset($_POST['Submit'])) {
$message_id = $_GET['message_id'];
echo "weeeeee" . $message_id;
}
[/code]

but when i click on the delete icon, it should echo that, but it doesn;t

anyone help me out please?

[trq]

No need to escape quotes unless your within php.

[code]
<td><input name='Submit' type='image' src='../index_images/delete.ico' ></td>
[/code]

[pouncer]

Sorry, i should have pasted more. it is within PHP, it just adds the records to a table with a delete.ico next to each record incase i want to delete the entry

[code]
          <?php
  $Me = $_SESSION['Username'];

  $Get_Messages = mysql_query("SELECT count(message_id) FROM private_messages WHERE To_='$Me'");

if (mysql_num_rows($Get_Messages) < 1) echo "You have no private messages.<br>";

else {
$Num_Messages = mysql_result($Get_Messages, 0, 'count(message_id)');
echo "You have a total of " . $Num_Messages . " private message(s)<br><br>";

echo "<img src='../index_images/read.gif'>" . " read message      " . "<img src='../index_images/unread.gif'>" . " unread message      " . "<img src='../index_images/delete.ico'>" . " delete message";

$priv = mysql_query("SELECT * FROM private_messages WHERE To_='$Me'");

echo "
<table width=90% cellpadding=0 cellspacing=3 border=0 align=center>
<tr>
<th></th>
<th bgcolor=#E1E4F2>Message</th>
<th bgcolor=#E1E4F2>Date sent</th>
<th></th>
</tr>";

while ($message_info = mysql_fetch_array($priv)) {
$message_id = $message_info['message_id'];
$message_from = stripslashes($message_info['From_']);
$message_subject = stripslashes($message_info['Subject']);
$message_datesent = stripslashes($message_info['Date_Sent']);
$message_read = stripslashes($message_info['Recipient_Read']);

if ($message_read == 1) $image = "../index_images/read.gif";
else $image = "../index_images/unread.gif";

echo "
<tr>
<td><img src=\"$image\"></td>
<td align=left bgcolor=#F5F5FF><a href=\"hghg\">Re: $message_subject</a><br>$message_from</td>
<td align=center bgcolor=#F5F5FF>$message_datesent</td>
<form method ='post' action='myprivatemessages.php' name='record'>
<td><input name='Submit' type=\"image\" src=\"../index_images/delete.ico\" ></td>
<input type='hidden' name='message_id' value='$message_id'>
</form>
</tr>";
}

echo "</table>";
}
  ?>
 
  <?php

  if (isset($_POST['Submit'])) {
$message_id = $_GET['message_id'];
echo "weeeeee" . $message_id;
}
  ?>
[/code]

it just doesnt want to echo when i click the delete icon

You're using the POST method, so you should be looking in the $_POST array for the message_id:
[code]<?php
$message_id = $_POST['message_id'];
?>[/code]

thanks, didnt work tho

all the code is within myprivatemessages.php

it doesnt even echo the 'weeeeee'

[boo_lolly]

yours looks like
[code]<form ='something.php'[/code]
it should be
[code]<form=\"something.php\"[/code]

no whitespace. escape doublequotes.

[pouncer]

just tried that..

[code]
<form method ='post' action=\"myprivatemessages.php\" name='record'>
<td><input name='Submit' type=\"image\" src=\"../index_images/delete.ico\" ></td>
<input type='hidden' name='message_id' value='$message_id'>
</form>
[/code]

but still, when i click the delete icon, it doesnt even echo anything

if (isset($_POST['Submit'])) {
echo "the delete was clicked!";
}

pouncer, Submit is empty, it has no value. Perhaps add
[code]<input name='Submit' type=\"image\" src=\"../index_images/delete.ico\" value="Submit">[/code]

[kenrbnsn]

At the start of the script "myprivatemessages.php" put in these lines:
[code]<?php
echo '<pre>$_GET: ' . print_r($_GET,true) . '</pre>';
echo '<pre>$_POST: ' . print_r($_POST,true) . '</pre>';
?>[/code]
This will dump the values being passed to your script from the form.

i gt this:

$_GET: Array
(
)

$_POST: Array
(
    [message_id] => 14
    [Submit_x] => 10
    [Submit_y] => 4
)

[kenrbnsn]

What browser are you using? When using an image as a submit button, MSIE passes the X & Y locations within the image back to the script, not the plain name.

Ken

[Jessica]

Ah, because it's an image, you can't just check Submit, you have to check the Submit_x and y. Try that.

Ken, jinx :-P

You might want to check the other value, instead of submit, or set another hidden or something, because of the image problem.

[pouncer]

ahh i see now :D

this worked!

[code]
  if (isset($_POST['Submit_x'])  && isset($_POST['Submit_y'])) {
$message_id = $_POST['message_id'];
echo "the delete was clicked on messageid: " . $message_id;
}
[/code]

:D Thanks guys, and if there is perhaps a better way, please tell me:p

[kenrbnsn]

You only have to check submit_x or submit_y, since if one is set the other will be also.

Thanks.

[code=php:0]
if (isset($_POST['Submit_x'])) {
$message_id = $_POST['message_id'];
echo "the delete was clicked on messageid: " . $message_id;
}
