How to open a link which was parsed in a div? - php

Question

My site parses a spanish dictionary and lets you search for more than one word at a time. If you look up "hola" you get the first div). Some words come up with suggestions, like "casa", instead of definitions like "hola":
And what i am looking for is this:
So, i would like to: when you click on the suggestions (like CASAR in the example I posted) to print the result in a div like HOLA. Here is the code used:
$words = array('word0','word-1');
function url_decode($string){
return urldecode(utf8_decode($string));
}
$baseUrl = 'http://lema.rae.es/drae/srv/search?val=';
$cssReplace = <<<EOT
<style type="text/css">
// I changed the style
</style>
</head>
EOT;
$resultIndex = 0;
foreach($words as $word) {
if(!isset($_REQUEST[$word]))
continue;
$contents = file_get_contents($baseUrl . urldecode(utf8_decode($_REQUEST[$word])));
$contents = str_replace('</head>', $cssReplace, $contents);
$contents = preg_replace('/(search?[\d\w]+)/','http://lema.rae.es/drae/srv/search', $contents);
echo "<div style='
//style
", (++$resultIndex) ,"'>", $contents,
"</div>";
}
I have tried with: $contents .= '' . $word . '<br/>'; But it didn't work nor I know really where/how to use it.

Okay, I'll use jQuery for the example because it will be the easiest to get the job done specially if you are new to programming.
NOTE: I DO NOT RECOMMEND USING JQUERY -BEFORE- LEARNING JAVASCRIPT -- DO IT AT YOUR OWN RISK, BUT AT LEAST COME BACK AND LEARN JAVASCRIPT LATER
First, read up on how to download and install jquery here.
Secondly, you will want something a little like this, let's pretend this is your markup.
<div id="wrapper">
<!-- This output div will contain the output of whatever the MAIN
word being displayed is, this is where HOLA would be from your first example -->
<div id="output">
</div>
<!-- This is your suggestions box, assuming all anchor tags in here will result in
a new word being displayed in output -->
<div id="suggestions">
</div>
</div>
<!-- Le javascript -->
<script>
// Standard jQuery stuff, read about it on the jquery documentation
$(function() {
// The below line is a selector, it will select any anchor tag inside the div with 'suggestions' as identifier
$('#suggestions a').click(function(e) {
// First, stop the link going anywhere
e.preventDefault();
// Secondly, we want to replace the content from output with new content, we will use AJAX here
// which you should also read about, basically we set a php page, and send a request to it
// and display the result without refreshing your page
$.ajax({
url: 'phppage.php',
data: { word: 'casar' },
success: function(output) {
// This code here will replace the contents of the output div with the output we brought back from your php page
$('#output').html(output);
}
})
});
})
</script>
Hopefully the comments will shed some light, you need to then set up your php script which will be sent a GET request. (for example, http://some.address.com/phppage.php/?word=casar)
Then you just echo out the output from PHP
<?php
$word = $_GET['word'];
// Connect to some database, get the definitions, and store the results
$result = someDatabaseFunctionThatDoesSomething($word);
echo $result;
?>
Hope this helps, I expect you have a lot of reading to do!
