Hi - I'm looking for help in getting all form fields from a html form, not just those fields preceding a submit button click.

I have a form which has multiple submit buttons located throught the form. For exampe, it might reside in the middle of the form, again a lines later, and again a few lines later.

When I do a

while(list($key, $value) = each($HTTP_GET_VARS) )


I get the $key/$value pairs for everything up to an including the submit button. However, I can see from the browser location bar that ALL forms args are being submitted, not just the ones up to a submit button which might be located, for example, halfway thru my list of fields.

I'm looking for help with capturing each and every $key/$valuepair, not a truncated version. And I want these in an array, preferable two arrays, one called $keyarray, and one called $valluearray.

Thanks in advance :-)

Try something like this:

PHP Code:


<?php

foreach ($_GET as $key=>$val)
{   
    echo "\$key = $key , \$val = $val <br />";
}   

?>

<form action="<?php $_SERVER['PHP_SELF']; ?>" method="get">

<input type="hidden" name="field1" value="this is field1" />

<input type="submit" name="submit1" value="this is submit1" />

<input type="hidden" name="field2" value="this is field2" />

<input type="submit" name="submit2" value="this is submit2" />

</form>

--ed

That gave me this error:

Parse error: parse error, unexpected T_VARIABLE

this seemed to work ...

$form_fields = array_keys($HTTP_GET_VARS);
for ($i = 0; $i < sizeof($form_fields); $i++) {

$thisField = $form_fields[$i];
$thisValue = $HTTP_GET_VARS[$thisField];
echo $thisField ." = ". $thisValue;
echo "<br />";

}

Hmm, that's weird, it parsed alright for me. What version of PHP you using?
