However, you want to select the "drop down" field based on "select" ID, let say you have this url : <a href="http://www.hoeffner.de/machform/embed.php?id=2&element_17=2" rel="nofollow">http://www.hoeffner.de/machform/embed.php?id=2&element_17=2</a> You already see this code around line 637: <pre><code>$option_markup .= "<option value=\"{$option->id}\" {$selected}>{$option->option}</option>\n";</code></pre> please add these code exactly above that line : <pre><code>if ((trim($_GET['element_17']) == $option->id) && ($element->id == '17') && ($_GET['id'] == '2')) { $selected = 'selected="selected"'; }</code></pre> it should select "Berlin-Marzahn" ... yuniar on "How can I set PHP variables in forms?" https://www.machform.com/forums/topic/how-can-i-set-php-variables-in-forms#post-3959 Wed, 10 Dec 2008 20:16:15 +0000 yuniar 3959@https://www.machform.com/forums/ Oops..sorry.

Sorry... no it did not wor here... when I open the form (which is actually an iframe of another page) directly like: /machform/view.php?id=2&element_17=10 there are no options available in the drop-down element. Something must still be wrong. Thank you for your effort and brilliant support.

Sorry I was a bit imprecise in this point: The iframe-form should been loaded with this url (on my opinion?!?): /machform/view.php?id=2&element_17=10 form id=2 drop-down select id=element_17 drop-down select value= 10 (for example) Because I do not have the variable "city" I changed it to this, but without success! The result was that no option were displayed. I must be wrong somewhere... <pre><code>if ((trim($_GET['element_17']) == $option->option) && ($element->id == 'element_17') && ($_GET['id'] == '2')) { $selected = 'selected="selected"'; }</code></pre> Hope you can help me with that...

For example drop down values are : -one -two -three around line 637 you will find : <pre><code>$option_markup .= "<option value=\"{$option->id}\" {$selected}>{$option->option}</option>\n";</code></pre> try to replace with <pre><code>if ((trim($_GET['city']) == $option->option) && ($element->id == '2') && ($_GET['id'] == '1')) { $selected = 'selected="selected"'; }</code></pre> nilsmierzynski on "How can I set PHP variables in forms?" https://www.machform.com/forums/topic/how-can-i-set-php-variables-in-forms#post-3692 Mon, 17 Nov 2008 15:47:44 +0000 nilsmierzynski 3692@https://www.machform.com/forums/ I would love to load the form with different option selection depending from where I open the form. For example: berlin.php with link to form.php?id=1&city=berlin ===> form.php: <SELECT><OPTION value="Berlin" selected> I know the PHP code, but I am not sure where I have to place the code to get it just in the form (ID) I want it to be. Thank you all Nils
