How to add parameters to a php script

[valonesal]

We are wondering how we would add parameters to the following script so that each section can be called separately.

<?php
// This is the content we want to display
$data = <<<EOT
<div class="topbar">
My Text goes here
</div>
EOT;
// Output JavaScript code to write the data
printf('document.write(unescape("%s"));',
  rawurlencode($data));
?>

so what we would like to do is be able to call a single section or div section by using something like "http://my website.com/thisscript?n=5" we just need to be able to output each section individually without the rest.

Thank you.

I would think you could just throw it into an if statement no?

if($something <<condition here>>){
$data = <<<EOT
<div class="topbar">
My Text goes here
</div>
EOT;
// Output JavaScript code to write the data
printf('document.write(unescape("%s"));',
  rawurlencode($data));  }
else { <<do something here>> }

Something like that maybe?

[valonesal]

Well unfortunately im relatively new to php so im not entirely sure what the above means.

If you could provide a little explenation that would be great.

[CFROG]

What sections do you want to call separately? Sections of the code itself?

[valonesal]

we just want to call the text in the div tags seperately

[CFROG]

Well you only have one div there. Do you want it to display if a certain condition exists, for example > if this button is clicked, show this div ? Not sure what you mean by displaying it separately.

[valonesal]

so if we use this

<?php
// This is the content we want to display
$data = <<<EOT
<div class="topbar">
My Text goes here
</div>
<div class="topbar1">
My Text goes here
</div>
EOT;
// Output JavaScript code to write the data
printf('document.write(unescape("%s"));',
  rawurlencode($data));
?>

We would like to be able to call and display each div separately. Or show the text inside the divs individually with a call to them.

[valonesal]

What we are trying to achieve it to update text on different pages with one file, so we need to have div 1 display on one page and div 2 display on another when we link to this file.

[CFROG]

First I would think you want to echo your html output if you are nesting it a <?php tag like so

<?php
// This is the content we want to display
$data = <<<EOT
echo '
<div class="topbar">
My Text goes here
</div>';

So if you click "link1" topbar div should show on that page and if you click "link2" topbar1 div should show on a different page?
?>

[valonesal]

ok when I do that it shows both of the messages how would I seperate them to call them differently?
Also I am not trying to use buttons to call them, I am using javascript to call the output and inject it into the html page.

[CFROG]

What does the script look like that you are inserting into the head of the document?

[CFROG]

Sorry, was going to say something else here but realized it didn't pertain to your problem

[valonesal]

Ok in short all I am trying to do is use one file to insert text dynamicly to update page, so here is what I am doing.

So all I need to be able to do is some how output the different sections so I can use links like such http://index.php?text=this to show the text from the specific div tag or id tag.

Im sorry this is hard but Im still in the begining stages of learning php.

[almostbob]

using :: file.php?text=this as example

if else

<?php
if (!$text) {die('No text selected');}
elseif($text='this') {echo '<div class="topbar">This Text goes here</div>'; }
elseif($text='that') {echo '<div class="topbar">That Text goes here</div>'; }
?>

switch / case

switch ($text) {
case '':
die('No text selected');
break;
case 'this':
echo '<div class="topbar">This Text goes here</div>';        
break;
case 'that':
echo '<div class="topbar">That Text goes here</div>';        
break;
}

[CFROG]

There ya' go, if anyone has the solution to your problem Almostbob is your guy. Sorry I couldn't be of more help, still a little confused about what you're trying to do.

[valonesal]

how will I be able to use it for urls?

[CFROG]

If you just want the text to show in your URL just incorporate it into your link

echo '<a href="my_link.php?text=".$text."">';

[almostbob]

<?php
if (!$text) {die('No text selected');}
elseif($text='this') {echo '<div class="topbar">anything you like, once php has processed it its just html goes here</div>'; }
elseif($text='that') {echo '<div class="topbar">anything else you like, once php has processed it its just html goes here</div>'; }
 
switch ($text) {
case '':
die('No text selected');
break;
case 'this':
echo '<div class="topbar">anything you like, once php has processed it its just html goes here</div>';        
break;
case 'that':
echo '<div class="topbar">anything else you like, once php has processed it its just html goes here</div>'; 
include ("./menu.php");

When I was asking about how I would use it in a link, I was wondering how I would call each section by a link so that only that section of text showed.

[CFROG]

I would think you would just use the link like

echo '<a href="my_link.php?text=".$text."">';

have the link point to the page your are updating and then use GET

$text=$_GET['text'];

Then use a conditional if statement like AlmostBob showed you to display the text according the value of $text passed through the URL

[valonesal]

the problem that I am having is that im using javascript to display this on html pages

[CFROG]

AlmostBob would the guy to help you there. Is the Java necessary or could you just code it differently using php?

[valonesal]

well I have the javascript part done its just this part that I need to get done. Now here is what the javascript tutorial said about the php part

The examples so far assume that every website would display the same syndicated content, but you can use parameters to customize the output for each of your syndication partners.

For example, if your PHP script accepted a parameter n, then you could specify n=5 when you fetch the JavaScript syndication file:

[valonesal]

At this moment the only thing I can get to display on his code is "No text selected" So im still working on getting it to display the sections of the php.

[CFROG]

Where it says you can specify n=5 that would be a variable in PHP like $n=5

[valonesal]

Even though Im not sure what a variable is well not completely anyways, but im guessing its the $text='this' in the code, but question is why it the code not working when it should be.

Oh and the $n=5 was just an example

Im so lost :( but i need to learn it so, thanks for your patience :)

[CFROG]

Yes, $text='this' is the variable. Actually $text is the variable and 'this' is it's value. There are many ways to assign a value to a variable. What part of your script is asking for a variable from php ?

[valonesal]

No part is asking for the variable, I just use javascript to pull information from a url, so I just need the script to be able to parse the information into sections.

From what I understand almostbobs script would allow me to pull information from the sections using script.php?text=this but when I try that it displays nothing.

Do you have any ideas why its not displaying anything when I believe it should be.

[CFROG]

Are you successfully getting it to pass a value through the URL?

[almostbob]

why javascript
javascript is blocked on a large proportion of the potential market
passing as a url, the page is being reloaded
best practice; prepare the page serverside, then you can be sure its working as intended
the whole thing appears to be able to be a single php script,
but the description of the task, is terribly incomplete,
post the code in whole there may be something simple

IF you want to integrate javascript and php examine AJAX
