PHP - Resize Image And Convert Its File Type

Folks,

I am building a membership script for 21 months now!!! That long!!!
Anyway, I need members to say infront of their cams a few things and then upload the vid file to the site (from the confirm_id.php page) where the member's sponsor (recruiter) will get the video copy to check if it's the real person with the real personal details or not. If true details, then sponsor verifies the member account. Else, unverifies it.
Now, I been testing my code. I uploaded an mp4 file. That should be ok but I get echoed:
"There was a problem uploading your video file $file_name! Make sure your file is an MP4 or a WAV file. You may try again now." 
Why ?

Not pasting the whole script as really long. Would do your head in.
Only pasting relevant part:

if($_SERVER["REQUEST_METHOD"] == "POST") 
    { 
        if(!isset($_FILES["id_verification_video_file"]))  //REtype
        { 
            echo "no isset";
        }
        else 
        { 
            $id_verification_video_file = $_FILES['id_verification_video_file']; //REtype
            //Feed Id Video Verification File Upload Directory Path. 
            $directory_path = "uploads/videos/id_verifications/"; 
            //Make Directory under $user in 'uploads/videos/id_verifications' Folder. 
            if(!is_dir("$directory_path" . "$user")) 
            {

                mkdir("$directory_path" . "$user", "$mode", TRUE); //Thanks Requinix for my "$mode" typo hint.
            }

            $Errors = Array(); //SHOULD I KEEP THIS LINE OR NOT ?

                //Move uploaded File to newly created directory on the server. 
                move_uploaded_file("file_tmp","$directory_path" . "$user/" . "$file_name"); 
                //Notify user their File was uploaded successfully. 
                echo "<font size ='5' font color ='red'><b>Your Video File \"$file_name\" has been uploaded successfully! You will get notified once your Id has been verified successfully.</b></color></size>"; 
                

Can you spot my coding error ?
Any other errors ?
How-about you show me code sample how you'd do it better and simpler with as much less lines of codes as possible ?

Hi Guys,

I have this script below which inserts the file name and path into my datebase and uploads the file into the customers folders (which is creates dynamically).

The is no error checking as I want it to be as flexible as possible but mostly(99.999%) the files I upload are JPEG and PDF's.

I would like my script to be able to resize the files above automatically to be smaller.

Please is this possible thanks!

Here is script:

I have a working image upload script that uploads, renames the file and adds filename to the database.

is it possible to include some sort of image resize code? if so can anyone point me in the right direction or better still show some example code and explain how it works etc.

below is my working code:

$errors = array();

$fileBaseName = substr($fileName, 0, strripos($fileName, '.'));

   // Get the extension from the filename.

I want to reduce a picture size from 600px * 500px to 60px * 50px size, then crop it become 50px *50px. I have two groups of codes, 1 is to reduce the size of image, other 1 is to crop the image. The problem is they works separately, how to combine this two groups of codes to make them work together? Below is my codes :

Code: [Select]
<?php
//codes of group A - Reduce the size of image from 600px * 500px to 60px * 50px   
    $save2 = "images/users/" . $image_name_2; //This is the new file you saving
    list($width2, $height2) = getimagesize($file) ; 
    $modwidth2 = 50; 
    $diff2 = $width2 / $modwidth2;
    $modheight2 = $height2 / $diff2; 
    $tn2 = imagecreatetruecolor($modwidth2, $modheight2) ; 
    $image2 = imagecreatefromjpeg($file) ; 
    imagecopyresampled($tn2, $image2, 0, 0, 0, 0, $modwidth2, $modheight2, $width2, $height2) ; 
    imagejpeg($tn2, $save2, 100) ; 

//codes of group B - Crop the image from 60px * 50px to 50px * 50px 
    $save3 = "images/users/" . $image_name_3;  
    list($width3, $height3) = getimagesize($file) ; 
    $modwidth3 = 60;  
    $diff3 = $width3 / $modwidth3;
    $modheight3 = $height3 / $diff3; 

    $left = 0; 
    $top = 0;

    $cropwidth = 50; //thumb size
    $cropheight = 50;

    $tn3 = imagecreatetruecolor($cropwidth, $cropheight) ; 
    $image3 = imagecreatefromjpeg($file) ; 
    imagecopyresampled($tn3, $image3, 0, 0, $left, $top, $cropwidth, $cropheight, $modwidth3, $modheight3) ; 
    imagejpeg($tn3, $save3, 100) ; //save the cropped image
?>
As you can see from 2 groups of codes above, 1st group resize the pic then save it to a folder. 2nd group of codes crop the pic then save it into the folder too. My question is ... After 1st group of codes resize the picture, is it necessary to save it into folder before I can crop it? If it is necessary, then I need to write new lines of codes to retrieve the resized pic from the folder for 2nd group of codes to crop it? If it is not necessary, after resizing the pic, how do I pass the pic to 2nd group of codes to crop it?

Hi.

I want to create a list of files in a directory. But I don't want all the files to be listed, only .gif, .jpg and .bmp.

Thanks!

I have this code which uploads fine but I am trying to limit the type of files users can upload.  For some reason this code still let any file type to be uploaded being very new to php any help would be Appreciated.

I have created a table called directories. Now basically I have two fields;

dirID (INT)
directory (VARCHAR)

now I am fully aware this might sound like more of an SQL question but I have three physical directories:

db/images/web1
db/images/web2

I have inputted them into the database but I was just wondering, how could I created a page which links those records to a directory. I want to have each row hyperlinked, with the output page displaying list of contents for each directory. How can I possibly achieve this please?

hello
I want download a file from another website and resize it to new size then reduce quality to 60% and save in on my host.
this is my code about download and reduce quality.
//images address
$images1 = textbetween('<a href="','"',$text0);
//save images
$im = imagecreatefromjpeg($images1); // original image
//reduce image quality
imagejpeg($im, "/public_html/static/images/book/".$imagename.".jpg" , 60); // save to new image, third value is quality (0-100) if not specified its the default (75)
can anyone help me to resize it?


thank you

I did a tutorial on uploading a profile pic and also did a tutorial on an image re-size class. The only thing is the tutorial on the re-size class is done without using a form which is pointless. Can someone help me integrate this into the profile pic tutorial? Here's a link to the re-size tutorial.

Hi,

I'm having to look hard for the right way to do this.

Basically the image is sent to the database, and is called to be put in a table, but the images are all different sizes, i would like them all one size, whats the best way to do this with my existing script:

Code: [Select]
<?php 
 error_reporting(E_ALL);
 ini_set("display_errors", 1);
 echo '<pre>' . print_r($_FILES, true) . '</pre>';

 
 //This is the directory where images will be saved 
 $target = "/home/users/web/b109/ipg.removalspacecom/images/COMPANIES"; 
 $target = $target . basename( $_FILES['upload']['name']); 
 
 //This gets all the other information from the form 
 $company_name=$_POST['company_name']; 
 $basicpackage_description=$_POST['basicpackage_description']; 
 $location=$_POST['location']; 
 $postcode=$_POST['postcode'];
 $upload=($_FILES['upload']['name']); 
 
 // Connects to your Database 
 mysql_connect("***", "***", "***") or die(mysql_error()) ; 
 mysql_select_db("***") or die(mysql_error()) ; 
 
 //Writes the information to the database 
 mysql_query("INSERT INTO `Companies` (company_name, basicpackage_description, location, postcode,  upload) VALUES ('$company_name', '$basicpackage_description', '$location', '$postcode',  '$upload')") ; 
 echo mysql_error();
 
 //Writes the photo to the server 
 if(move_uploaded_file($_FILES['upload']['tmp_name'], $target)) 
 { 
 
 //Tells you if its all ok 
 echo "The file ". basename( $_FILES['upload']['name']). " has been uploaded, and your information has been added to the directory"; 
 } 
 else { 
 
 //Gives and error if its not 
 echo "Sorry, there was a problem uploading your file."; 
 } 
 ?>
