PHP : Easy gallery

[eWhabs]

PHP : Main
I already made that tutorial 2 weeks ago in french and I decided to translate it :)

So, did you ever want to create a gallery on your site, but you don't want to create a page for each image? Here's the solution!!

I will take as example an image gallery , but you could use this code for anything (videos, flash, etc)

1. First of all, upload your images with simple names (ex: gallery1, gallery2, etc…)

2. Create a page where you will put the links to your different images.

3. Create a new page with the *.php file type.

4. Now I will explain you the codeyou have to put!

First, the code:

<img src= "
<?
$src = $_GET [“image”]
echo $src
? >
“/>

Now let us analyze the code!

<img src= "

Quite obvious, the code to put an image (only the beginning)

<?

Opens the PHP code.

$src = $_GET [“image”]

Defined the variable “src”. In your URL, you will have to put, afterthe name of page (ex: image.php), this: ”? image=name of the image.jpg " The $_GET function will seek in the URL the value of “image” (defined in the URL with”? image=URL ") Then, if my image has the name “image1.jpg”, the URL would have to look like that:

www.mysite.com/image.php?image=image1.jpg.

echo $src

Usse the ECHO function to write the URL of your image (image1.jpg).

A principle that it is necessary to understand in PHP is that all the code is executed on the host's computer and is sent has the user in plain HTML.

? >

Closes the PHP code

“/>

Closes the image code

Then, the output of this code would be, after execution on the host's computer:

<img src= " image1.jpg "/>

A very simple code which saves you hours (minutes?) of work!

Obviously you can replace the code outside of the PHP by anything you want, I just explained the basics!

This is a very simple way of using register globals to make your gallery. I like the tutorial :)

Wouldn't that return an error?

Should use instead:

<img src="<?php $src = $_GET["image"]; echo $src; ?>" />

+ security concerns - the script doesn't check the directory of the path... you could easily send a string such as ../../images/private/img.jpg and the script would return it.

It's extremly basic, and the user can view any image they want, and dig through your directorys.

Or you could make it simple by changing to this:

<img src="<?php echo $_GET['image'];?>" />

hey, I just thought I would post my version of a gallery with no DB, it requires the pictures to be called pic-X.JPG but, it works well for me, and includes next and previous buttons to provide a more gallery feel.

function disp($pid) {
if (file_exists("pic-".$pid.".JPG")) {
echo "<img src=pic-".$pid.".JPG>";
echo "<br><br>";
if (file_exists("pic-".($pid-1).".JPG")) {
echo "Previous &nbsp; ";
}
if (file_exists("pic-".($pid+1).".JPG")) {
echo "Next";
}
} else {
echo "this file doesn't exist, try here";
}
}
if ($_GET['pid']) {
disp($_GET['pid']);
} else {
disp(1);
}

hey, sorry I had no idea that the forum would butcher my code like that.

if you want a clean version there is one here:

function disp($pid) {

      if (file_exists("pic-".$pid.".JPG")) {
#
            echo "<img src=pic-".$pid.".JPG>";
#
            echo "<br><br>";
#
            if (file_exists("pic-".($pid-1).".JPG")) {
#
                  echo "Previous &nbsp; ";
#
            }
#
            if (file_exists("pic-".($pid+1).".JPG")) {
#
                  echo "Next";
#
            }
#
      } else {
#
            echo "this file doesn't exist, try here";
#
      }
#
}
#
 
#
### code for displaying:
#
 
#
if ($_GET['pid']) {
#
      disp($_GET['pid']);
#
} else {
#
      disp(1);
#
}

Use code tags.

Dude, it's from fuckin '06 - There weren't code tags back then
