[SOLVED] image page

[Sir Softsand]

Hi, I got a folder on my FTP called "images"

I have a page. I want to show all of the images in the directory image on that page without keep updating that page with HTML <img src="...

My friend said you could do this with PHP, is that true?

 

Thanks in advance, Sir Softsand

Yes that is true. You can use pho's readdir function to read all the files/folders in the images folder. Then using a while loop you can echo out the HTML to display the images on your webpage.

 

Before you take on this project of yours make sure you know the basics of PHP. It will be better for you to learn the basics of PHP, such as variables, functions, loops, arrays, data types, superglobals ($_POST, $_GET etc) before you get started. Also make sure your hosting account has PHP enabled -check with your host.

<?php

$handle = opendir('/images');

    while ($file = readdir($handle)) {
            echo "<img src=\"$file\" alt=\"\" /><br />\n";
    }

closedir($handle);

?>

 

Untested, I suggest you read up on the functions used though

[Sir Softsand]

Sorry, I made a mistake, the dir's name is: avatars

This code doesn't work:

<?php

$handle = opendir('/avatars');

    while ($file = readdir($handle)) {
            echo "<img src=\"$file\" alt=\"\" /><br />\n";
    }

closedir($handle);

?>

Any errors? Try CHMODing /avatars to 777.

[Sir Softsand]

avatars dir is now 77 CHMOD, don't get errors, the images just don't show up.

[chigley]

View the source and paste the output please.

[wildteen88]

Use the following path:

./avatars/

and not

/avatars

 

If you are running it on a UNIX based platform, PHP will treate / as the root (of the hard drive) and so it will try to access a folder called avatars in the root of the hard drive. The root will be most probably out of bounds to you. What you want to do is place a period before the slash (./) this will tell PHP to look in the current directory and not the root.

$handle = opendir('./images');

    while ($file = readdir($handle)) {
            echo "<img src=\"$file\" alt=\"\" /><br />\n";
    }

closedir($handle);

 

this works for me, but the images are not comming out.  When I click properties on the image, it shows www.mysite.com (IE the site I have them on) and nothing else.

For the image to work it needs to be:

 

$handle = opendir('./images');

    while ($file = readdir($handle)) {
            echo "<img src=\"images/$file\" alt=\"\" /><br />\n";
    }

closedir($handle);

$handle = opendir('./images');

closedir($handle);

 

That worked, thanks!

Ok, I know i clicked solved, but now I got a problem. The avatars showed up every time. But I changed host, and just transferred all data from the other host I ad before. The avatars still showed up, but when I refreshed the page, 2 avatars dissapeared, when I refreshed again more avatars dissapeared, then I refreshed again and they were all gone!

[chigley]

Have you changed the permissions of /avatars on the new server?

[Sir Softsand]

Permissions changed while transferring data, going to check.

[Sir Softsand]

I CHMODed the avatars dir back, but they still don't show up.

[Sir Softsand]

They show up again

[Sir Softsand]

And for some reason, they disappear now again

[Sir Softsand]

Can anyone help me?

Either give a link to the page where we can view the generated code, or post the generated code here.  We really can't tell what might be happening looking at php fragments, the source of your problem is within the generated html page.

 

Appearing and disappearing sounds like you're seeing cached versions.

[Sir Softsand]

Here's the link:

I see a whole series of images.  The first two lines below obviously have a problem, the rest are fine.  Check your php code to see where the first two lines are coming from to fix them.

 

<br /><img src="avatars/." alt="" / > 

<img src="avatars/.." alt="" / > 
<img src="avatars/cirkels1.jpg" alt="" / > 
... more images follow

[Sir Softsand]

Yes, you see all the images, but after a while refresh the page, do it again and again and eventually some will disappear.

[Sir Softsand]

I can see them again now, but it's only a matter of time untill they'll start disappearing again.

[Sir Softsand]

Here's my php code:

<?php

include('overall_header.html');

$handle = opendir('./avatars');

    while ($file = readdir($handle)) {
            echo "<img src=\"avatars/$file\" alt=\"\" / > \n";
    }

closedir($handle);

include('overall_footer.html');

?>

[AndyB]

No. If they appear once and you don't change the code then they'll always appear (unless it's hosted on a dreadfully bad server and you have a really bad internet connection, in which case you might have problems seeing them).

 

The problem with the code you posted is that it doesn't ignore . and .., i.e. folder structure in the folder you're reading.  That's where the incorrect html code originates.  Take a closer look at user notes on the manual page on readdir - or use glob() instead.
