Using PHP to insert an mage into a page based on the url or page meta title

Topic:

PHP Scripting Language;;

Hello php experts,

I am working on a website built with php and I am looking for some code that would put an image in a page, based on the title of a page or its url.

For example, if the page had this url:
http://www.website.com/banana
A picture of a banana would appear on the page (obviously from the image folder)
banana.jpg

Or if the page had this url:
http://www.website.com/ripe-apple
A photo of an apple would appear on the page.
ripe-apple.jpg

Or if the page had this url:
http://www.website.com/bart-simpson
A photo of bart simpson would appear on the page
bart-simpson.jpg

I'm not a programmer, but I assume it could be done with placeholders. ?????

The website is Joomla which has a way for me to include external php (for example a snippet) to be inserted into an article.

The site is built using the following:

Mysql 5.5.23-55
Database collation: utf8_general_ci
Php: 5.3.27
Web server: Apache
Jooma: 2.5.14 Stable [ Ember ] 01-August-2013 14:00 GMT

Thanks for any help or suggestions.

Sorry to have to put you through the testing, but I don't have the environment needed to validate the code. Try replacing the existing PHP with this:

<?php // RAY_temp_rowby.phperror_reporting(E_ALL);// CAPTURE THE SCRIPT NAME AND APPEND AN IMAGE SUFFIX$uri = '/images' . $_SERVER['REQUEST_URI'] . '.jpg';// CONSTRUCT THE HTML IMAGE TAG$img= '<img src="'. $uri. '" alt="'. $_SERVER['REQUEST_URI']. '" />';// WRITE THE TAG TO THE BROWSERecho $img;?>

Looks like we can find the information we need here (excerpt from the orange URL). Now it's just a matter of formatting it into a URL that works.

["REQUEST_URI"]=>
string(7) "/orange"

It should not be looking for a standalone file; it should be integrated into the original script.

Can you please install this script at "orange" (like the other script is installed at "banana"). It will produce a lot of unwanted output, but I will be able to see some clues in the data. I hope.

Hi, Rowby.

Line 7 says this:
?php // RAY_temp_rowby.php

Change that to this:
<?php // RAY_temp_rowby.php

Line 23 says this:
echo $img;$img;

Change that to this:
echo $img; ?>

Not sure if this is 100% right but I think we are getting closer.

Hi Ray,

I am using this plugin "Sourcerer" (from a very reliable joomla programmer) to paste the php right onto the page:

http://www.nonumber.nl/extensions/sourcerer/userguide

On that URl you will see how his plugin lets me paste php directly onto a joomla "article": Below is a snippet from the above url's documentation

{source}<?php    echo 'This text is placed through <strong>PHP</strong>!';?>{/source}

So for your code, this is what I put on the article (not into the source code, but directly in the article.

Looks like the <?php tag that starts the PHP interpreter was some how damaged because there is PHP code written into the HTML stream.

Let's try this. Please post the entire script that generates this page. Just copy/paste into the code snippet. If there are any passwords or anything like that, feel free to obscure them, but post as true, correct and complete version of the script as you possibly can. I'll see if I can figure out a place to put the PHP code.

Hi Ray

Obviously I'm doing something terribly wrong here (with your updated code:

http://rowbytesting.com/RAY_temp_rowby.php

and http://rowbytesting.com/banana

Is the RAY_temp_rowby.php the php code the banana page is supposed to pull from? If so would I need some placeholder code on the actual banana page that links to the RAY_temp_rowby.php script?

Or can I put your entire php code in the banana page -- which is what I tried to do with bad results.

Rowby

Expert: Ray Paseur replied at 2024-08-04 12:24:40

OK, what we are probably missing is the '/images/' part of things. Try this script instead and see if the output makes more sense.

?php // RAY_temp_rowby.phperror_reporting(E_ALL);// CAPTURE THE SCRIPT NAME AND APPEND AN IMAGE SUFFIX$uri = '/images' . $_SERVER['PHP_SELF'] . '.jpg';// CONSTRUCT THE HTML IMAGE TAG$img= '<img src="'. $uri. '" alt="'. $_SERVER['PHP_SELF']. '" />';// WRITE THE TAG TO THE BROWSERecho $img;

Hi Ray,

Thanks for helping!

Not 100 percent sure what to do with your script.

I have tried this: http://rowbytesting.com/RAY_temp_rowby.php

I also inserted the code into my joomla page (with a plugin that allows me to insert php into an article: http://rowbytesting.com/banana

Of course that didn't work. I realize I am missing something :)

So just so I am clear

If the page is named http://rowbytesting.com/ banana it would automatically put in the image already located in /images/banana.jpg into a placeholder on the page.

If the page is named http://rowbytesting.com/apples-and-orange it would put in the image already located in /images/apples-and-oranges.jpg into a placeholder on the page.

I want the php to "see" the url and automatically put the image into the placeholder.

There will be only one image per page.

Expert: Ray Paseur replied at 2024-08-04 11:36:40

Install this using any script name you want, and run it, then use "view source" to look at what it produces. You might want to use ltrim() to remove a leading slash from the script name - that will depend on your file system structure.

<?php // RAY_temp_rowby.phperror_reporting(E_ALL);// CAPTURE THE SCRIPT NAME AND APPEND AN IMAGE SUFFIX$uri = $_SERVER['PHP_SELF'] . '.jpg';// CONSTRUCT THE HTML IMAGE TAG$img= '<img src="'. $uri. '" alt="'. $_SERVER['PHP_SELF']. '" />';// WRITE THE TAG TO THE BROWSERecho $img;

Hi Duncan,

My first question on this thread was "I am working on a website built with php and I am looking for some code that would put an image in a page, based on the title of a page or its url."

So what I am doing here, after thinking about it, is to request a solution based on its url, not on its title. It would make it much easier for me. I can make one master page and do a "save as" and create a new url -- which would automatically pull in the new image.

If I have to go in an put in new meta data it would almost be as much work as manually putting in the image.

Which is why I have refined my question to request the php bring in the photo, to a placeholder within the html, based on the url of the page.

Thanks

Hi Cd&

These URLS are not being indexed by Google. They are special pages set up for Google Adwords campaigns. They will not be public pages. Only seen within the Google adwords campaign

I am setting up a bunch of pages that are customized to different cities where I want to target business.

For example, I have a Los ANgeles page, a Sacramento Page, a San Diego page.

The text on the page will be the same. But for the Los ANgeles page I will have a photo of something related to Los Angeles. For Sacramento there will be a sacramento photo.

So the only difference will be the photo.

I have about 30 -40 pages I need to set up and I just want to do clones of my master page, with the only change being the different photo being pulled in.

For example, www.foobar.com/los-angeles will include the los angeles photo, www.foobar.com/sacramento will include the sacramento photo.

If Google should index the page for whatever reasons that is great, but that is not the purpose of my particular project -- which is for google adwords.

Rowby

Expert: COBOLdinosaur replied at 2024-08-04 08:13:46

Why would you change the url? Once it is indexed by the search engines, if you want a different version you clone it to keep the old version, or you do a redirect to a new version.

Either way you still end up with a new page unless you don't care about Google rankings.

Author: rowby replied at 2024-08-04 08:04:16

Hi all --

As I think about this -- the ideal solution would be pulling the image based on the url instead of meta data. Then if I change the url it would automatically let me change the image instead of having to go 7n and change the meta data each time.

I will be back at my computer within the hour
And will be able to check your suggestions.

Thanks!

You say the meta title identifies the unique page so you are generating a custom value. Just add a line right after it:
<?php
$imgtarget='images/banana.png';
?>

Then a the point where the image needs to be you use:

<img src="<?php echo $imgtarget; ?>" />

The variable $imgtarget should be global in the page so even if you are generating the image from an include the variable should be valid and you don't need to do a lot of coding.

Just done and tested on my browser and works
using following code and redirect page according to the
name of photo detected from browser bar address , for example,
http://www.website.com/ripe-apple.php
will redirect to ripe-apple.bmp ,

you can change bmp extentsion in the echo statement below for other ext
and replace "bmp" by such as jpg, gif, png...etc.

<?php//echo $_SERVER['SCRIPT_FILENAME'];$fnd=$_SERVER['SCRIPT_FILENAME'];$mline=explode("/",$fnd);//echo "==".count($mline)."===";$kline=explode(".",$mline[count($mline)-1]);//echo "==".$kline[0]."===";//Switch code below  is just up to you, or no needswitch ($kline[0]) {    case "banana" :        break;    case "ripe-apple":        break;    case "bart-simpson":          break;	case "image":	break;} // header("Location: http://mysite.com/ee/".$kline[0]."html");echo '<html><head><title>Image photo</title></head><meta http-equiv="Content-Type" content="text/html; charset=Big5"><meta http-equiv="Refresh" content="0; url='.$kline[0].".bmp".'"/></html> ';?>

Hi

Thanks for responding.

The title would be the meta title. There would be no special visible title on the page. Every page would have the same title;

So we are talking about the url or the meta title. Or it could be other meta data I could add to the page, if that makes it easier.

I prefer that it pull an image based on the url, rather than meta title, but if meta data is easier for your to work with that that would be fine.
