    <p>I'm using the Contact Form 7 plugin on wordpress to collect data inputted in the fields, I'm now looking to set up some validation rules using this neat extension: <a href="http://code-tricks.com/contact-form-7-custom-validation-in-wordpress/" rel="nofollow">http://code-tricks.com/contact-form-7-custom-validation-in-wordpress/</a> <br> What I'm after is to only allow one word only in the text field (i.e. no whitespace) and this one word has to begin with the letter 'r' (not case sensitive).<br> I've written the no white space rule as follows:</p> <pre><code>//whitespace if($name == 'WhiteSpace') { $WhiteSpace = $_POST['WhiteSpace']; if($WhiteSpace != '') { if (!preg_match('/\s/',$WhiteSpace)){ $result['valid'] = true; } else { $result['valid'] = false; $result['reason'][$name] = 'Invalid Entry.'; } } } </code></pre> <p>Is it possible to incorporate the second rule into this also? So no whitespace, and the word must begin with the letter 'r'? Any suggestions would be greatly appreciated!</p> <hr> <p>EDIT: seems <code>core1024</code> answer does work, but only one of them:</p> <pre><code> //FirstField if($name == 'FirstField') { $FirstField = $_POST['FirstField']; if($FirstField != '') { if (!preg_match("/(^[^a]|\s)/i",$FirstField)){ $result['valid'] = true; } else { $result['valid'] = false; $result['reason'][$name] = 'Invalid Entry.'; } } } //__________________________________________________________________________________________________ //SecondField if($name == 'SecondField') { $SecondField = $_POST['SecondField']; if($SecondField != '') { if (!preg_match("/(^[^r]|\s)/i", $SecondField)) { $result['valid'] = true; } else { $result['valid'] = false; $result['reason'][$name] = 'Invalid Entry.'; } } } </code></pre> <p>I want to use this code twice, once to validate the first character being <code>a</code> on one field the second instance with the first character being <code>r</code> on another field. But it only seems the <code>SecondField</code> validation rule is working.</p>

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.
