how to autopopulate a form w/ PHP

obsidianchrysalis · 11-09-2005, 03:28 PM

hey all. i have a bit of a problem getting a form to populate with information from a list of $_GET variables.

i can get text fields to populate with the values from the variables, but i can't get <SELECT> fields to austo select to the values.

any help would be appreciated....

Can you share how you currently display the <select> options in your PHP script? Are the options generated dynamically or are they static? There are a few ways to do it.

Here's a basic way,

<select name="field1">
<option value="myvalue1" <? if ($_GET['field1'] == 'myvalue1') echo 'selected';?>>
<option value="myvalue2" <? if ($_GET['field1'] == 'myvalue2') echo 'selected';?>>
</select>

yes the way -RJ- has suggested is the way to go about it even if they are dynamically created you can still do it the way -RJ- mentions you just use the same variable where the value is anjd also in the if statement such as:-

<option value="<?PHP echo $variable1 ?>" <?PHP if ($_GET['field1'] == $variable1) echo 'selected';?>>

Just a note however although short tags work (which is what -RJ- used) it is best practice not to use them so that your code is as portable as possible.

Code:

<?php
$options[] = "myvalue1";
$options[] = "myvalue2";
$options[] = "myvalue3";
$options[] = "myvalue4";
echo '<select name="field1">';
foreach($options as $option) {
if($_GET['field1']==$option) { $blaat = ' selected="selected"'; } else { $blaat = ''; }
echo '<option value="'.$option.'"'.$blaat.'>'.$option.'</option>';
}
echo '</select>';
?>

I think that's about it what you need for loong lists of options.
