PHP - Generating Waveform From Audio File

Hey all,

So I have .caf files that are recorded from my iOS applications and uploaded to my server.  Ultimately I want to play these recordings within my website using jPlayer (a jQuery plugin: http://www.jplayer.org), which means they need to be converted from the .caf format.  The encoding cannot be done on the mobile device, or so I am told, being that it is too processor intensive.  This leaves the webserver...

So far I've had very little luck finding any way to convert the file using PHP.  I assumed that it would be easy enough to use something like LAME to encode the caf into a mp3.  I've seen a few cryptic references to doing exactly this in my google searches, but no definitive information.

Can anybody shed some light on the situation?

Thanks.

Hi,

i have the following code:

where i want the sound to only play during the false part of the IF statement

but currently it always plays on every reload, and even if the IF = true

any ideas? ive tried autoplay="0" also

 

Thanks

 

	<embed src="beep.wav" autostart="false" width="0" height="0" id="sound1"
enablejavascript="true">

+

<script>
function PlaySound(soundObj) {
  var sound = document.getElementById(soundObj);
  sound.Play();
}
</script>

+

		if( isset( $json['Data'] ) ){
			echo "<b>Success</b>";
			echo "</br>";
			echo $data.' x ' .$tqty;  
			echo "</br>";
			
		} else {
			echo "Error";
			echo "</br>";
			echo $json['Message'];
			echo '<script> PlaySound("Sound1"); </script>';
		}

 

Hi.  So I've coded many a file upload form and never had any trouble.  Until now.  For some reason when I try to upload MP3 files, I'll hit submit and the page just reloads.  Once it does so, the file upload field is once again blank.  What's odd is that images and documents upload just fine.  It's only audio tracks that cause the page to reload and clear.  My php.ini max file upload size is at this point set to 100M, and the files I'm trying to upload are under 10M.  Any ideas?  Here's the form code, just to post it-- pretty basic.  I'm at a loss here....  Any ideas would be appreciated.  Thanks very much.



<form action="test.php" enctype="multipart/form-data" method="POST"/>


   <input type = "file" name = "audio" />
   
   <p><input type ="submit" name="submit" value="do it."/><p>

</form>

There is a section in my site in which i will need to give the user 3 options:

Generate Specific User Text As:
            1.  pdf
            2. .doc
            3. .txt
            4. print in html

The 4th option is simple. The other three are completely new to me.

I know little bit about fopen, fwrite and fclose, however these are commands that write files to the server. I need to write files to the users computer.

Is the best way for this to be:
 1. the user clicks .txt
 2. the .txt is written to the server
 3. the .txt is then downloaded to the users computer by the user
 4. the .txt is then deleted from the server

All 4 steps to be done with one click from the user.

Might there not be traffic problems if lots and lots of users are doing this at the same time?

Any pushes in right direction here would be great, there seems to be hundreds of sites saying different solutions

hi guys, im trying to resize and save a thumbnail version of images uploaded to my site in a sub folder (thumbs).

I've currently got:


$image=imagecreatefromjpeg($filepath);

list($width, $height) = getimagesize($filepath);

$new_width = 200;
$new_height= 150;

$image_p=imagecreatetruecolor($new_width, $new_height);

imagecopyresampled($image_p, $image, 0, 0, 0, 0, $new_width, $new_height, $width, $height);

// Save the image
imagejpeg($image_p, '/thumbs'.$filepath);

// Free up memory
imagedestroy($image_p);


but it appears to do nothing, but it also doesn't return any errors?
could someone help me out please?
thanks!

Hi,

I've written some code to take information from an SQL database and write it out in the RSS format (Although it doesn't validate).

The problem is i'd like the page to have the .rss (or .xml) file extension, I'm not sure if there's any advantages in having this but thought i'd ask.

I've got the following code:

Code: [Select]
<?php 
header('Content-type: text/xml');
print '<?xml version="1.0"?>';
print '<rss version="2.0">';
        print '<channel>';
include("phpfunctions.php");
db_connect();

//select all from users table
$select="SELECT title, link, description FROM news";
$result = mysql_query($select) or die(mysql_error());

//If nothing is returned display error no records
if (mysql_num_rows($result) < 1) {
die("No records");
}

//loop through the results and write each as a new item

while ($row = mysql_fetch_assoc($result)) {
    $item_title = $row["title"];
    $item_link = $row["link"];
    $item_desc = $row["description"];

        print '<item>';
           print '<title>' . $item_title . '</title>';
            print '<link>' . $item_link . '</link>';
            print '<description>' . $item_desc . '</description>';
        print '</item>';


}
print '</channel>';
print '</rss>';

?>


This seems to work fine as i get what i expect and i'm assuming i can do the same to output .xml but is there a way to have it in a proper .rss / .xml file so that an aggregator or someone could read this properly.

Cheers,

Reece

Does anyone know of a free php library to create pdf417 2d barcodes?

Hi All -

I wanted to know if there is any existing script to generate an eticket when a user books a ticket through a website.

Thanks

As a complete newbie, I'm not sure Ive got the terminology right in my subject header. But this is what I am trying to do.

I have a soccer stats site with data entered into each of numerous 'seasons', accessible via a drop-down menu, as he
http://www.fleethistory.co.uk/stats/matches.php

Now regardless of what season I select, the URL will stay the same as above. What I want to do is have users go direct to a particular season from a link without having to use the drop-down. How would I generate a unique URL for each of the seasons listed in the drop-down?

Don't know if you need the PHP code, but here it is just in case:

OK, what I am trying to do is generate a dynamic variable name.

I want to setup a foreach statement that will generate variable names based on an array of data.

$numbers = array('one', 'two', 'three', 'four', 'five', 'six', 'seven');

foreach ($numbers as $number) {

}


What I need, is for a bunch of variables to be generated and filled with content.

$variable_one_label = "Blah";
$variable_two_label = "Blah Again";

How can I generate the dynamic variable based on the array value?

Hi all,

I want some help regarding my banking project. I have a customer registration form in my project.After successfully completion of the form users have to click on the "Open Account" button.Thereafter a customer id(Auto increment value) should be generated.It was stored in the database where other form details are also being stored. How can i call to this one by one customer id's??

Heshan,

I searched online and seen some complex c and c# code which I didn't understand much of. But how do I generate an array with all string combinations based on length and from a charset?

E.g. charset = {'a', 'b', 'c'}

Length = 2.

Then it should generate first all 1-char strings:

a
b
c

Then all 2-char strings:

aa
ab
ac
ba
bb
bc
ca
cb
cc

And then all added to the same array.

I think there's some way of doing it with recursion but to me it's like thinking with a 4th dimension my mind can't grasp this logic!

I am using this code to evaluate whether checkboxes within a group have been selected:

    
    function IsChecked($chkname,$value)
    {
        if(!empty($_POST[$chkname]))
        {
            foreach($_POST[$chkname] as $chkval)
            {
                if($chkval == $value)
                {
                    return true;
                }
            }
        }
        return false;
    }

Now, I've decided that I want to add a message upon finding NO SELECTED checkbox items, but it is not functioning as desired.

 if(empty($_POST[$chkname]))
	  {
	    echo("You didn't select any checkboxes.");        
        }

How can I get this or something similar to trigger?

I'm trying to generate a page with javascript in it with PHP.  But the quotations are causing me problems, I need a third set of quotations.  Here is the part I am having trouble with:


echo"<div class='level'>Edit:</div><div class='box'><input type = 'text'  size='50' name='cat' value='$cat'/> <b><input type='button' value='+ Details' onclick='document.getElementById('rev$clicker').style.display='block';'/></b> </div><br>";


When I view the html it comes out onclick='document.getElementById('rev$clicker').style.display='block';'

I can't use "" quotations for 'block' and 'rev$clicker' because that would exit from the echo and I can't exit php because I need the $clicker variable.
