Disappearing values

wessie

Hi all,

I'm having a problem with self-processing forms (forms that have action=$PHP_SELF) losing their values. What i do is store the values of certain variables in hidden fields. I give the hidden fields the same name as the variables. But as soon as i submit the form, i check the source after the page has been rendered and i see that the values in the hidden fields have disappeared.

Eg.
Before submit
<form method="POST" action="/app_ed/frmUpdate.php">
<input type="hidden" name="strNewText" value=" This is a test message on the dev webserver ">
<input type="hidden" name="strOldText" value=" This is a test message ">
<input type="submit" name="btnUpdateSubmit" value="Submit" value='Yes/No' onclick='return confirm("Are you satisfied with the new message?");'>
</form>

After submit
<form method="POST" action="/app_ed/frmUpdate.php">
<input type="hidden" name="strNewText" value=" ">
<input type="hidden" name="strOldText" value=" ">
<input type="submit" name="btnUpdateSubmit" value="Submit" value='Yes/No' onclick='return confirm("Are you satisfied with the new message?");'>
</form>

What could've caused the values to disappear?

If u want your form to return in the same page just leave your form action empty.
U should have something like this:

<form method="POST" action="">
<input type="hidden" name="strNewText" value="<?php if (!empty($_POST['strNewText'])) echo $_POST['strNewText'];?>">
<input type="hidden" name="strOldText" value="<?php if (!empty($_POST['strNewText'])) echo $_POST['strOldText'];?>">
<input type="submit" name="btnUpdateSubmit" value="Submit" value='Yes/No' onclick='return confirm("Are you satisfied with the new message?");'>
</form>

This may be your generated html, but it is no use to us here. We need to see the php code that you use to generate this html before we can answer that question.

Thanx for the replies guys.

Bogu, i copied your code directly into my script and i got the following error.

Parse error: parse error, unexpected T_IF in XXXXX on line XX

that's normally an absence of a semi-colon or a misplaced/missing quote (' or ") but i can't see anything wrong with your code! It's strange really.

Bogu,

I dunno why but i just re-copied your code into my script and it appears to be working (sought of). It seems like the variables are still disappearing after i submit the form 😕 😕 😕
