    <p>In my photo portfolio admin page, I've built a tool to caption, keyword and credit each photo. Until now, I've dynamically listed multiple forms, each containing a submit button. With 20+ photos/forms on the page, this can be a boring job and was hoping to build on this by adding a button at the bottom of the page to submit all.</p> <p>I went ahead and built what I thought was a good approach and looped through all the forms one-by-one and posted the data to a PHP page using AJAX. This worked fine, but like I mentioned, with 20+ photos, it's running 20 AJAX requests and 20 SQL updates, and now feel this is a poor effort.</p> <p>I'm now looking at other ways that involve looping through each form, creating an array or object, and sending it in one request and have one nifty SQL query to update all rows at once.</p> <p>This is where I'm at now. I'm struggling to get the form fields into a readable and usable object for my PHP to read.</p> <p><strong>MY FORM STRUCTURE</strong></p> <pre><code>&lt;form name="12344"&gt; &lt;div class="input_wrap"&gt; &lt;textarea id="12344_caption"&gt;&lt;/textarea&gt; &lt;/div&gt; &lt;div class="input_wrap"&gt; &lt;input type="text" id="12344_keywords" /&gt; &lt;/div&gt; &lt;div class="input_wrap"&gt; &lt;input type="text" id="12344_credit" /&gt; &lt;/div&gt; &lt;div class="input_wrap"&gt; &lt;input type="text" id="12344_credit_url" /&gt; &lt;/div&gt; &lt;/form&gt; &lt;form name="12345"&gt; &lt;div class="input_wrap"&gt; &lt;textarea id="12345_caption"&gt;&lt;/textarea&gt; &lt;/div&gt; &lt;div class="input_wrap"&gt; &lt;input type="text" id="12345_keywords" /&gt; &lt;/div&gt; &lt;div class="input_wrap"&gt; &lt;input type="text" id="12345_credit" /&gt; &lt;/div&gt; &lt;div class="input_wrap"&gt; &lt;input type="text" id="12345_credit_url" /&gt; &lt;/div&gt; &lt;/form&gt; </code></pre> <p><strong>MY JQUERY SO FAR</strong></p> <pre><code>var photo_annotations = {}; $('form').each(function(i) { var id = $(this).attr('id'); var caption = $('#'+id+'_caption').val(); var keywords = $('#'+id+'_keywords').val(); var credit = $('#'+id+'_credit').val(); var credit_url = $('#'+id+'_credit_url').val(); // create object to post photo_annotations[id].push({}); (help) } $.ajax({ type: 'POST', url: 'ajax/save-annotations.php', data: { json: JSON.stringify(photo_annotations) } }); </code></pre> <p>This is the kind of data I'd like to construct:</p> <pre><code>photo_annotations = { "12344": { "caption": "This is a caption for the photo ID 12344.", "keywords": "Keyword1, Keyword2, Keyword3", "credit": "John Doe", "credit_url": "http://www.johndoe.com" }, "12345": { "caption": "This is a caption for the photo ID 12345.", "keywords": "Keyword4, Keyword5, Keyword6", "credit": "Joe Bloggs", "credit_url": "http://www.joebloggs.com" } } </code></pre> <p>I'm struggling to get my form fields into JSON correctly, in the format I showed you above. I hope that somebody could show me how to achieve this format.</p>

    1. COWhy don't you just wrap it all in a single form tag? Or you could just pass `$('form').serialize()`

    3. COYou can have multiple submit buttons in a single form, each with a different name, and just check which submit button was clicked server side.

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.
