Send to: customer.service [at] appnitro.com I'll check it. msfbiz on "Dynamic Radio Button Value" https://www.machform.com/forums/topic/dynamic-radio-button-value#post-11435 Wed, 16 Feb 2011 19:16:21 +0000 msfbiz 11435@https://www.machform.com/forums/ I have tried the code, but it's not working. Also shouldn't it be <pre><code>if($option->id == 2 && $GLOBALS['my_radio'] == 2){ $option->is_default = true; }</code></pre> since we want the radio value 2 to be selected? In any case, I've tried with both == 1 and ==2 but couldn't get it to work. msfbiz on "Dynamic Radio Button Value" https://www.machform.com/forums/topic/dynamic-radio-button-value#post-11433 Wed, 16 Feb 2011 17:55:31 +0000 msfbiz 11433@https://www.machform.com/forums/ Great, thanks!!! yuniar on "Dynamic Radio Button Value" https://www.machform.com/forums/topic/dynamic-radio-button-value#post-11423 Tue, 15 Feb 2011 17:50:16 +0000 yuniar 11423@https://www.machform.com/forums/ Ok, so let say you have a radio button like this: <pre><code><input id="element_2_1" name="element_2" class="element radio" type="radio" value="1" /> <label class="choice" for="element_2_1">First option</label> <input id="element_2_2" name="element_2" class="element radio" type="radio" value="2" /> <label class="choice" for="element_2_2">Second option</label> <input id="element_2_3" name="element_2" class="element radio" type="radio" value="3" /></code></pre> and your form code + variable is like this: <pre><code><?php $my_radio = 2; require("/home/machform/machform.php"); $mf_param['form_id'] = 159; $mf_param['base_path'] = 'http://example.com/machform/'; display_machform($mf_param); ?></code></pre> and our goal is to choose the second radio button (id = 2) when the value of $my_radio variable is 2 as well. So, all you need to do is to edit your "includes/view-functions.php" file. Search around line 493 for this code: <pre><code>foreach ($element->options as $option){</code></pre> exactly below that code, add this: <pre><code>if($option->id == 2 && $GLOBALS['my_radio'] == 1){ $option->is_default = true; }</code></pre> that should do it. msfbiz on "Dynamic Radio Button Value" https://www.machform.com/forums/topic/dynamic-radio-button-value#post-11416 Mon, 14 Feb 2011 21:43:49 +0000 msfbiz 11416@https://www.machform.com/forums/ I'm using the advanced form code. No, the PHP variable is NOT passed as a URL parameter, it's defined in the PHP code of the page at the top. yuniar on "Dynamic Radio Button Value" https://www.machform.com/forums/topic/dynamic-radio-button-value#post-11414 Mon, 14 Feb 2011 16:33:08 +0000 yuniar 11414@https://www.machform.com/forums/ Are you using the advanced form code or the standard (iframe)? Also, is the PHP variable being passed as URL parameter? msfbiz on "Dynamic Radio Button Value" https://www.machform.com/forums/topic/dynamic-radio-button-value#post-11403 Sat, 12 Feb 2011 01:26:15 +0000 msfbiz 11403@https://www.machform.com/forums/ I'd like to choose the value of a radio button according to the value of a PHP variable defined in the page where the Machform form is embedded. How do I need to modify view-functions.php file? Thanks! Mike
