    <p>I allow people to submit images and I need to limit their submits to not more than 5 in a day. I just need your help to construct the sql code as rest of things are prepared. I would rather not use solutions based on sessions and cookies. IP based solution is not rock-solid either but for me it is okay and better than the other two. Just so you know the site is built on wordpress and I know nothing about mysql. </p> <p>EDIT : <em>I am already trying to construct the code below in EFFORTS UPDATE. Please take a look.</em></p> <hr> <p><strong>HERE IS WHAT I AM DOING</strong> : I already have a table in mysql for this function, named someprefix_limit_uploads. I will log the ip and date of the person who will use the form first time and save it to database on form submit, with help of hidden fields, example - <code>&lt;input type="hidden" name="uploader_ip" value="&lt;?php echo $uploader_ip;?&gt;"/&gt;</code>. Then I will insert the values to the table with something like below, since I am using wordpress so my code will look like so :</p> <pre><code>global $wpdb; require_once('../../../wp-load.php'); $upload_date = strip_tags($_POST['upload_date']); $uploader_ip = strip_tags($_POST['uploader_ip']); $table_name = $wpdb-&gt;someprefix . "limit_uploads"; $wpdb-&gt;insert( $table_name, array( 'rec_upload_date' =&gt; $upload_date, 'rec_uploader_ip' =&gt; $uploader_ip )); </code></pre> <hr> <p><strong>HERE IS WHERE I AM STUCK</strong> : Now for the code in the page which contains the form, I need to wrap the form in <code>if_statement</code>. Basically the script must hide the form after 5 submits within 24 hour. Here is an example of what the final code may look like.</p> <pre><code>global $wpdb; $results = $wpdb-&gt;get_results("COUNT xyz xyz xyz xyz xyz xyz xyz xyz xyz "); if(//there are more than 5 submits from same ip on same day) { echo "no more than 5 uploads allowed."; } else { &lt;form id="upload-images" action="" method="POST"&gt; //contents of the form &lt;/form&gt; } </code></pre> <hr> <blockquote> <p>Bottomline: It must be evident by now that I need help with the second block of the code. As I am not even sure I should use COUNT or SELECT, if yes then how. I will appreciate a little help here, also please point out if there is something wrong in my approach.</p> </blockquote> <hr> <p><strong>EFFORTS UPDATE :</strong></p> <p>I figure the sql query has to be something like this but missing some elements :</p> <pre><code>SELECT COUNT(*) **missing_some_code_here** FROM someprefix_limit_uploads WHERE rec_uploader_ip = $uploader_ip; AND rec_upload_date = $upload_date; </code></pre> <p>and then in my page</p> <pre><code>if (**missing_some_code_here** &gt; 5) { echo "no more than 5 uploads allowed."; return; } </code></pre>

    1. CONot sure what's the problem, but maybe you just need `$wpdb->get_var` instead of `get_results`? It will return single value, which is the counter from the SQL query you provided. Then you can simply compare this counter whether it's not greater than 5. I assume `rec_upload_date` is a date, not datetime?

    2. CO@sebapalus at this moment the problem is my sql code is incomplete. I am just looking to replace `**missing_some_code_here**`. What do I need to put there in order to get the count? Yes `rec_upload_date` is just a date not datetime as I just need to check the date.

    3. COYou don't need to put there anything. `SELECT COUNT(*) FROM table WHERE condition` is just enough

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.
