    <p>Well this is quite nice solution, a working one. I've seen much worst around.<br> Only a few notes. </p> <ul> <li>it has some unnecessary validations, say <code>contains_bad_str(body);</code> is useless. And whole "bad words" approach at all. Newline test is enough</li> <li>just a rule: <code>DO NOT TALK TO STRANGERS</code>. Never talk to possible attacker, providing them with any feedback. All these "Suspected injection attempt" are childish and more of it - it supply an attacker with information they can use. Always send just 500 HTTP error in all these cases and nothing else.</li> <li>you're using pretty unusual way of error handling. I can't understand the difference between these code snippets</li> </ul> <p>why the first one just sets a variable </p> <pre><code>if(trim($_POST['emailTo']) == '') { $hasError = true; </code></pre> <p>and second one prints an error and exits?</p> <pre><code>if (!is_valid_email($email)) { echo 'Invalid email submitted - mail not being sent.'; exit; } </code></pre> <p>Will you provide a fair user with any feedback on error occurred? Something like "Please fill all required fields"?</p> <ul> <li><p>I wouldn't make user supplied e-mail subject but rather some hardcoded sentence, like <code>Feedback from ".$_SERVER['HTTP_HOST']</code>. I'd like to distinguish feedback messages in my mailbox from the regular ones. (I wouldn't make that fancy reply-to feature either, but it's my own preference)</p></li> <li><p>stripslashes thing. Why only message? Aren't other fields behave the same? And at least you have check get_magic_quotes_gpc() before applying. I'd make it automated, at hte top of the script, both stripslashes and trim, just in the loop over $_POST array.</p></li> </ul>

    1. COHow do I redirect to 500 http? Thats just based off the tutorial I read should it not be set as a variable and then ext is that bad practice? Can you show me a better way? Also I dunno about the magic quotes thing can you explain how or show me an example? Sorry I am still very noob at this Thanks

    2. CO@Jacinto not redirect. just send a 500 error using `header()` function and exit. Aside from tutorials - how do you think your form should look and behave? Just from the users point of view? Did you happen to use such a forms on the other sites? What is your own opinion? magic quotes are well explained in the manual, just google for `php magic quotes`

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.
