    <p>I have a big form that contains X amount of posts that has 15 fields per post along with 1 hidden field. </p> <p>Let's assume I have 14 posts. This means my form would send 211 fields (14x15 fields plus 1 hidden field).</p> <p>The user does not have to fill in all fields.</p> <p>I want to count the number of posts that the form sends but I seem to be running into difficulty.</p> <p>Using count($_POST) returns 152. This leads me to believe that count() is ignoring empty fields.</p> <p>As a result, using a formula such as (count($_POST) - 1) / 15 would return the wrong result (10.0666) and is inefficient should the number of fields change in the future.</p> <p>So, does anyone have any ideas as to how to get the proper count of my posts?</p> <p>My form looks like so:</p> <pre><code>&lt;form name="scraped" action="&lt;?php echo str_replace( '%7E', '~', $_SERVER['REQUEST_URI']); ?&gt;" method="post"&gt; &lt;input type="hidden" name="OSscraper_hidden" value="N"&gt; &lt;?php $inpCnt = 0; foreach($articles as $item) { ?&gt; &lt;input type="text" name="title_&lt;?php echo $inpCnt; ?&gt;"&gt; &lt;input type="text" name="name_&lt;?php echo $inpCnt; ?&gt;"&gt; &lt;input type="text" name="url_&lt;?php echo $inpCnt; ?&gt;"&gt; &lt;input type="text" name="img_&lt;?php echo $inpCnt; ?&gt;"&gt; &lt;input type="text" name="pet_&lt;?php echo $inpCnt; ?&gt;"&gt; &lt;input type="text" name="color_&lt;?php echo $inpCnt; ?&gt;"&gt; &lt;input type="text" name="value_&lt;?php echo $inpCnt; ?&gt;"&gt; &lt;input type="text" name="height_&lt;?php echo $inpCnt; ?&gt;"&gt; &lt;input type="text" name="weight_&lt;?php echo $inpCnt; ?&gt;"&gt; &lt;input type="text" name="hair_&lt;?php echo $inpCnt; ?&gt;"&gt; &lt;input type="text" name="eyes_&lt;?php echo $inpCnt; ?&gt;"&gt; &lt;input type="text" name="race_&lt;?php echo $inpCnt; ?&gt;"&gt; &lt;input type="text" name="phone_&lt;?php echo $inpCnt; ?&gt;"&gt; &lt;input type="text" name="address_&lt;?php echo $inpCnt; ?&gt;"&gt; &lt;input type="text" name="zip_&lt;?php echo $inpCnt; ?&gt;"&gt; &lt;?php $inpCnt++; } ?&gt; &lt;input type="submit" value="Submit"&gt; &lt;/form&gt; </code></pre>

    1. COIt might be suprise for you but you can pass array thru POST as it gonna be ideal solution for you. And `action=""` attribute is not necessary if you want to send data to same page. [EXAMPLE](https://gist.github.com/4650062). And your POST count will be `count($_POST['article']) * count($attrs)`;

    2. COcount() doesnt ignore anything. as a programmer, you must use some basic debugging to accomplish your tasks. maybe `print_r($_POST);` or `var_dump($_POST);` can help you get started.

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
