    <p>If you submit this data to the database, please take a look at the escape functions for your database.</p> <p>That is, for MySQL there is <a href="http://php.net/mysql_real_escape_string" rel="noreferrer">mysql_real_escape_string</a>.</p> <p>These escape functions take care of any characters that might be malicious, and you will still get your data in the same way you put it in there.</p> <p>You can also use prepared statements to take care of the data:</p> <pre><code>$dbPreparedStatement = $db-&gt;prepare('INSERT INTO table (htmlcontent) VALUES (?)'); $dbPreparedStatement-&gt;execute(array($yourHtmlData)); </code></pre> <p>Or a little more self explaining:</p> <pre><code>$dbPreparedStatement = $db-&gt;prepare('INSERT INTO table (htmlcontent) VALUES (:htmlcontent)'); $dbPreparedStatement-&gt;execute(array(':htmlcontent' =&gt; $yourHtmlData)); </code></pre> <p>In case you want to save different types of data, use <code>bindParam</code> to define each type, that is, an integer can be defined by: <code>$db-&gt;bindParam(':userId', $userId, PDO::PARAM_INT);</code>. Example:</p> <pre><code>$dbPreparedStatement = $db-&gt;prepare('INSERT INTO table (postId, htmlcontent) VALUES (:postid, :htmlcontent)'); $dbPreparedStatement-&gt;bindParam(':postid', $userId, PDO::PARAM_INT); $dbPreparedStatement-&gt;bindParam(':htmlcontent', $yourHtmlData, PDO::PARAM_STR); $dbPreparedStatement-&gt;execute(); </code></pre> <p>Where <code>$db</code> is your PHP data object (PDO). If you're not using one, you might learn more about it at <em><a href="http://php.net/book.pdo" rel="noreferrer">PHP Data Objects</a></em>.</p>

    3. COAn even better solution to the SQL injection problem is to use parametrized queries. That gets rid of the need to escape by hand completely.

Querying!

 
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.

SQuiL has stopped working due to an internal error.

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