image upload

[ayok]

Hi guys,

I have this script to resize the image

<?php
function change_pic($pic_name)
{
    header("Content-type:image/jpeg");

    $im_src = imagecreatefromjpeg($pic_name);
    $width_src = imagesx($im_src);
    $height_src = imagesy($im_src);

    $width_dst = 100;
    $height_dst = 100;
    $quality = 60;

    //resize process
    $im = imagecreatetruecolor($width_dst, $height_dst);
    imagecopyresampled($im, $im_src, 0, 0, 0, 0, $width_dst, $height_dst, $width_src,
        $height_src);

    imagejpeg($im, $pic_name, $quality);
    imagedestroy($im_src);
    imagedestroy($im);
}

if ($fupload_type = "image/pjpeg" || $fupload_type = "image/jpeg")
{
    copy($fupload, "./$fupload_name");
    change_pic($fupload_name);
}
else
{
    echo "File must be JPEG";
}?>

 

The codes resize the uploaded pic to 100X100 px from the original pic.

 

However, I want to modify this script so I can resize into two size and put it in different folder. I can put the original pic with the original size in a folder, but how can I have two resized pic like, say, 100X100 and 300X300?

 

Thank you,

Save the original to a folder.  Open, resize it, save that somewhere.  Close it.  Repeat the process for your other size.  In fact, you might be able to resize it twice without even closing it.  Where are you getting stuck?

Thank you phpknight,

 

I've tried your advice to save the original folder first, and open it to resize it. But I don't know how to open and resize the saved files. Could you tell me how?

 

Thanks,

try this

<?php
function change_pic($pic_name, $newname, $width=100, $height=100, $quality=60)
{
//not sure why the head as we're saving to file!
    //header("Content-type:image/jpeg");

    $im_src = imagecreatefromjpeg($pic_name);
    $width_src = imagesx($im_src);
    $height_src = imagesy($im_src);

    $width_dst = $width;
    $height_dst = $height;
    $quality = $quality;

    //resize process
    $im = imagecreatetruecolor($width_dst, $height_dst);
    imagecopyresampled($im, $im_src, 0, 0, 0, 0, $width_dst, $height_dst, $width_src,
        $height_src);

    imagejpeg($im, $newname, $quality);
    imagedestroy($im_src);
    imagedestroy($im);
}

if ($fupload_type = "image/pjpeg" || $fupload_type = "image/jpeg")
{
    copy($fupload, "./$fupload_name");
    change_pic($fupload_name, "./".$fupload_name,300,300);
    change_pic($fupload_name, "./100".$fupload_name,100,100);
}
else
{
    echo "File must be JPEG";
}?>

 

this code will create the 300 sized image and the 100 sized one..

 

Note the file name of the 100 with have 100 prefixed.. as i don't know where you wanted it stored

Thanks MadTechie,

I'll try this.

not sure why the head as we're saving to file!

 

is the header unnecesarry?

[MadTechie]

Nope, the header would be needed IF you have the php as the image but your send the image resource to the file not the screen

[ayok]

I see..

Thanks MadTechie, it works now.

 

However, I still have a question regarding uploading image. The script is working on localhost with IE. It uploads and resizes the picture, but if I test on Opera, it's not uploaded. Do you know why?

 

Thanks,

ok

you need to add some quotes

i think thats all of them!

session_start();
if(!empty($namauser) AND !empty ($passuser))

<OPTION VALUE='0' SELECTED>--Choose Category--";
$tampil=mysql_query("SELECT * FROM category ORDER BY id");

while($data=mysql_fetch_array($tampil))
{
	echo "<OPTION VALUE='$data[id]'>$data[name]";
}
echo "</OPTION></SELECT></td></tr>
<tr><td>Upload:</td> <td>
<input type='file' name='fupload'></td></tr>
</table>
<INPUT TYPE='SUBMIT' VALUE='Add'>

</FORM><a href='foto2.php'>Show and delete pictures</a><BR>

the script works fine in localhost, but when I tried in my webserver, i got this error: "Allowed memory size of 8388608 bytes exhausted (tried to allocate 6400 bytes) "

 

Why is that?

 

thanks,

ayok

[MadTechie]

Oh boy.. thats due to the server setup.. try to override it

 

change

$im_src = imagecreatefromjpeg($pic_name);

to

set_time_limit ( 0 ); //reset timeout timer
ini_set('memory_limit', '30M'); 
$im_src = imagecreatefromjpeg($pic_name);

 

let hope you don't join GaryDT's thread

 

[ayok]

Wow.. it works.. you're just great.

Thank you very much!

 

Cheers,
