Problem on PHP Tutorial: Automatic Image Gallery tutorial

Post by ijohnrussel »

Hi master's of PHP, I have a problem with one of your tutorials about automatic image galleries.
Maybe its just me, but every time I load the page the error icons show instead of the actual image.
Please help me :)

Could you right click on the page and click 'view source'

Just paste a snippet of whats there, not the whole thing. :)

I'll just send the codes I copy on tutorial...
Because when I view the source code only the HTML code is shown alongside the alt array thing...
Thanks.

I'm making a photo sharing website and I include this thing into my page so that people, well,
know who's currently registered on my webpage :)

Thanks

I'm still a tad unsure,
But try editing line 87;

Try replacing <img src=\"?img/{$images}\" alt\"{$images}\" />
With <img src=\"?img={$images}\" alt\"{$images}\" />

(That was ?img/{$images} to ?img={$images})

Query strings (the question marks in URLs) are not like directories. They use the equals operator.

Hmm,

Get rid of the line with $image in it,
and replace it with

[syntax=php]foreach(glob("*.{jpg,JPG,jpeg,JPEG,png,PNG,gif,GIF}", GLOB_BRACE) as $file){
$image[] = basename($file);
}[/syntax]

And lower down in the file, around line 83 down, change those {$images} to {$image}.

I think the problem was that you needed to state each part of the array, or it will just return the words 'Array".

[syntax=php] <?php

foreach($images as $image){
if (file_exists("./thumbs{$image}")){
echo "<a href=\"\"><img src=\"images/{$images}\" alt\"{$images}\" /></a>";
}else{
echo "<a href=\"\"><img src=\"?img/{$images}\" alt\"{$images}\" /></a>";



}
}

?>[/syntax]

$images is an array. You need to use $image when you echo.

[syntax=php] <?php

foreach($images as $image){
if (file_exists("./thumbs{$image}")){
echo "<a href=\"\"><img src=\"images/{$image}\" alt\"{$image}\" /></a>";
}else{
echo "<a href=\"\"><img src=\"?img/{$image}\" alt\"{$image}\" /></a>";



}
}

?>[/syntax]

I am also fairly sure that you need a slash between thumbs and {$image} here:
[syntax=php] if (file_exists("./thumbs{$image}")){[/syntax]

don't quote me on that though. Try it for yourself.

If you look at the image location "?img=5054193870_a648423b1e_o.jpg" it looks right, so if you paste that into your browser to actually view the thumbnail it might tell you why it's not generating one.
