that has nothing to with that case, ofcourse the $file_url is above my video tag! Besides, do i need to specify the type attribute when i use video tag og audio tag?
-
it doesnt work, when i specify the type attribute? why?
do i even need it?
it looks something like this:
<video width="320" height="240" controls> <source src="<?php echo $file_url;?>" type="video/mp4"> <source src=<?php echo $file_url;?>" > Your browser does not support the video tag. </video>
$file_url = "videos/2014042727116180637260000009088958.mp4";

$haystack = array("gif");$fileParts = array("extension" =>"GIF", nr2 => "JPG");$fileParts = $fileParts['extension'];$fileParts = strtolower($fileParts[0]);if(in_array($fileParts, $haystack)){ echo "right";} else { echo "false";}

i have here a tekst field and a button, that interacts with php using ajax
$status_ui = '<textarea id="statustext" onkeyup="statusMax(this,250)" placeholder="What's new with you '.$u.'?"></textarea>'; $status_ui .= '<button id="statusBtn" onclick="postToStatus('status_post','a',''.$u.'','statustext')">Post</button>';
But i get some sort of an error, which i dont know why is there
i get all the variables using the postToStatus function, and then send them to a php script using:
ajax.send("action="+action+"&type="+type+"&user="+user+"&data="+data);
in the php script i have an if statement
if($_POST['type'] != 'a' || $_POST['type'] != 'c')
{
echo "type_unknow";
exit;
}
it doesnt say anything about $_POST['type'], but when i run print_r i can see that the $_POST['type'] is set

duplicate audio tags
in HTML/XHTML
Posted
this code shows me duplicate audio tags, why?
$mp3 .= "<audio width='320' height='240' controls>n"; $mp3 .= "<source src='$file_url' type='audio/mpeg'>n"; $mp3 .= "</audio>n"; $show .= "<div>n"; $show .= "$mp3 <br> Tittel: $tittel <br>n <span style='float:left;'>Description:</span>n <div style='border:1px red solid;overflow:hidden;width: 100px; height:20px;'>$description</div>n"; $show .= "</div>n <br>";
it is supposed to show 1 file form the DB then a break line, but instead shows 2 of the same audio on line with each other.
