[SOLVED] PHP Help

[timbo8]

Hi, my name is Tim and I am just starting to learn PHP. But I need some help.

I want, when a user goes to the page /images.php?id=*, the script will open up an external text file, and save the text at line (id) to the variable $image. It will then open up another external .txt file, and save the text at line (id) to the variable $title.

I realise that this may be hard, but please help me.

Thanks in advance, Tim

Downlaod PHP manual in chm format.

 

 

http://in.php.net/get/php_manual_en.chm/from/a/mirror

 

Now refer functions fopen,fread,fwrite,fputs,fgets,file() ............. from manual.

Could you provide more detail. I am not quite understanding what you mean by 'and save the text at line (id) to the variable $image

 

Where is (id)? how would (id)  match a line in the external text file.

[timbo8]

id is a number, so it would be images.php?id=1, then 2 for the next page etc

(id) is the value of ?id=

Look at a pagination tutorial, i think thats what your looking for, they have some good ones on this site.

Tim - you need to explain what you are trying to do in far more detail than we have at present.

 

I want, when a user goes to the page /images.php?id=*, the script will open up an external text file, and save the text at line (id) to the variable $image.

 

What 'text' and where does it come from?

What structure does this external text file have? Examples, please.

 

The better you explain what you are trying to accomplish, the more likely it is that someone here will provide a solution - or suggest a better way of doing what you're hoping to do.

ok, the first text document will look like:

/images/imagename.jpg

/images/anotherimagename.jpg

/images/logoforsite.gif

 

it will list down image locations.

 

the second text document will look like:

Title for Image1

Title for Image2

Title for Image3

 

it will list the name of each image.

 

So, when they go to /images.php?id=3

 

it can display the image located at line 3, and display the title located at line 3

[wildteen88]

So the id corresponds to a line in the text files? correct?

 

try this simple bit of code:

<?php

if(isset($_GET['id']) && is_numeric($_GET['id']))
{
    // this holds the line number for our image/title in the txt file
    $i = ($_GET['id'] - 1);

    // file grabs every line in a document in to an array
    // read more on file here:
    // http://www.php.net/file
    $path = file('paths.txt');
    $title = file('titles.txt');

    $html = '<b>' . $title[$i] . '</b><br />
<img src="' . $path[$i] . '" title="' . $title[$i] . '" />';

    echo $html . '<hr />';
}

?>
Choose an image to be displayed:<br />
<a href="?id=1">Get image #1</a>
<a href="?id=2">Get image #2</a>
<a href="?id=3">Get image #3</a>

 

This code gets the paths of the images from a file call paths.txt and the titles for the image from titles.txt

Thank you wildteen88, that is exactly what I needed, and it works like a charm.
