    <p>I'm working on setting up a condition on my web page whereby 1 of 2 things may happen;</p> <p>1) The user posts a youtube link by itself, no other text, and that link is turned into an embeded video on the page.</p> <p>2) Any other kind of post is posted as a regular message, skipping everything in the preceding condition.</p> <p>I have some syntax set up that posts embeded video just fine (first condition), posts text and creates clickable hyperlinks just fine (second condition), but fails if someone tries to post a youtube link along with any other text. It fails because the code that controls condition 1 is not specific enough. Both conditions are processed like this;</p> <pre><code>if(strpos($message,"youtube.com/watch?v=")) { $message = '&lt;iframe width="420" height="315" src="' . str_replace('/watch?v=','/embed/',$message) . '"&gt;&lt;/iframe&gt;'; mysqli_query($db_conn,"insert into feed_messages (userid, subject, message) values ('$useridvalue', '$subject', '$message');") or die("".mysql_error()); $messageid = mysqli_query($db_conn,"select last_insert_id();") or die("".mysql_error()); $messageidvaluearray = mysqli_fetch_assoc($messageid); $messageidvalue = implode(" " , $messageidvaluearray); mysqli_query($db_conn,"insert into feed_recipients (messageid, userid) values ('$messageidvalue', '$useridvalue');") or die("".mysql_error()); foreach($_SESSION['recipientlist'] as $recipient) mysqli_query($db_conn,"insert into feed_recipients (messageid, userid) values ('$messageidvalue', '$recipient');"); header('Refresh: 0; URL=mypage.php'); } else { function make_links_clickable($message) { return preg_replace('!(((f|ht)tp(s)?://)[-a-zA-Zа-яА-Я()0-9@:%_+.~#?&amp;;//=]+)!i', '&lt;a href="$1" target="_blank" STYLE="TEXT-DECORATION: NONE"&gt;&lt;b&gt;$1&lt;/b&gt;&lt;/a&gt;', $message); } $message = make_links_clickable($message); </code></pre> <p>My question is; how can I make the first if statement more strict so that if it only sees the string "youtube.com/watch?v=" alone, then it executes its code block, otherwise if it see anything else accompanying it, then it can be processed by the else statement?</p> <p>Any help is appreciated. Thank you.</p>

    2. COHi Mark, can a wildcard be added at the end of the link? This statement is too specific. If the link, https://www.youtube.com/watch?v=examplevideo is put in a message, I would like the statment to match right up to the = sign.

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.
