save drop down list seelcted value in page load

[greedyisg00d]

I have a form which have a 1 text field and 3 drop down list in it. My problem is whenever I hit the submit button and redirect it to the same page the value of the selected drop down list is set again to default (Select one). Thus the user will need to select one by one again. Any idea or sample code so that I can analze it?

Thanks

You could use a session variable, or an array in this case;

When receiving the POST data:

$_SESSION['selects'][1] = $_POST['select1'];
$_SESSION['selects'][2] = $_POST['select2'];
$_SESSION['selects'][3] = $_POST['select3'];

Redirect back to form

...and then, in your form:

<select name='select1'>
	<option value='lorem'<?php if($_SESSION['selects'][1] == "lorem") echo " selected='selected'"; ?>>Lorem</option>
	<option value='ipsum'<?php if($_SESSION['selects'][1] == "lorem") echo " selected='selected'"; ?>>Ipsum</option>
	<option value='dolor'<?php if($_SESSION['selects'][1] == "dolor") echo " selected='selected'"; ?>>Dolor</option>
</select>

<select name='select2'>
	<option value='lorem'<?php if($_SESSION['selects'][2] == "lorem") echo " selected='selected'"; ?>>Lorem</option>
	<option value='ipsum'<?php if($_SESSION['selects'][2] == "lorem") echo " selected='selected'"; ?>>Ipsum</option>
	<option value='dolor'<?php if($_SESSION['selects'][2] == "dolor") echo " selected='selected'"; ?>>Dolor</option>
</select>

<select name='select3'>
	<option value='lorem'<?php if($_SESSION['selects'][3] == "lorem") echo " selected='selected'"; ?>>Lorem</option>
	<option value='ipsum'<?php if($_SESSION['selects'][3] == "lorem") echo " selected='selected'"; ?>>Ipsum</option>
	<option value='dolor'<?php if($_SESSION['selects'][3] == "dolor") echo " selected='selected'"; ?>>Dolor</option>
</select>

^ Not tested in any form, don't even remember if it's selected='selected' or something else right now, but you get the idea. 🙂
