    <p>I am trying to set the image src inside a hidden variable that is passed from my form. When I output the variable is "undefined". I am pretty new to Javascript and not sure what the problem could be. My error is on line:</p> <p><code>document.sampleForm.image.value = "images/"+img.attr('src')+"";</code></p> <p>Javascript:</p> <pre><code>$('tr', '#target').each(function () { var tr = $(this); html += '&lt;center&gt;&lt;tr&gt;'; $('td', tr).each(function () { var td = $(this); if (!td.is('td.header')) { var img = $('img', td); var text = $('textarea', td).val(); html += '&lt;td style="width: 33%;"&gt;'; html += (img.length) ? '&lt;img src="' + img.attr('src') + '" style="display: block; max-width: 100%;" /&gt;' : '&lt;div style="width: 100%;"&gt;&lt;/div&gt;'; document.sampleForm.image.value = "images/"+img.attr('src')+""; document.forms["sampleForm"].submit(); html += '&lt;/td&gt;'; } }); html += '&lt;/tr&gt;&lt;/center&gt;'; }); </code></pre> <p>HTML:</p> <pre><code>&lt;table id="target"&gt; &lt;form id="sampleForm" name="sampleForm" action="test.php" method="post"&gt; &lt;tr&gt;&lt;center&gt; &lt;td class="logo" colspan="3"&gt; &lt;h3&gt;Choose Header&lt;/h3&gt; &lt;div class="img-container"&gt;&lt;input type="hidden" name="image" id="image" value=""&gt;&lt;/div&gt; &lt;/td&gt; &lt;/center&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td style="height:auto;"&gt; &lt;?php $test = mysql_query("SELECT id, title FROM tmpl2"); echo "&lt;select class='image_select' id='logo_option' name='logo_option[]' multiple='multiple'&gt;"; while ($row = mysql_fetch_assoc($test)) { echo "&lt;option value='".$row[id]."'&gt;$row[title]&lt;/option&gt;"; } echo "&lt;/select&gt;"; ?&gt; &lt;/td&gt; &lt;/tr&gt; &lt;tr&gt;&lt;center&gt; &lt;td class="logo" colspan="3"&gt; &lt;h3&gt;Choose Logo&lt;/h3&gt; &lt;div class="img-container"&gt;&lt;/div&gt; &lt;/td&gt; &lt;/center&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td style="height:auto;"&gt; &lt;?php $test = mysql_query("SELECT id, title FROM tmpl2"); echo "&lt;select class='image_select' id='header_option' name='header_option[]' multiple='multiple'&gt;"; while ($row = mysql_fetch_assoc($test)) { echo "&lt;option value='".$row[id]."'&gt;$row[title]&lt;/option&gt;"; } echo "&lt;/select&gt;"; ?&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </code></pre>

    1. CODoing a `submit` inside a loop doesn't make sense. When you submit the form, the page reloads, and your script stops.

Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
