Pagination Help

Hey Guys & Girls,

 

Okay, so here's my little issue.  I'm running a WordPress site with a custom PHP script using JSON/CURL/API pulling info from an API.

 

All is good in the world in this respect.  However, the API listings that are returned are only returned in a 50 item block.  The API doesn't allow for more than 50 items per call.

 

So, what I'm looking for is a way to paginate my results so that if there are more than 50 items in the API call, it will allow the user to click to page 2, 3, 4 etc.

 

Here's my code:

<?php
//functions relating to wordpress go here:
//----------------------------------------
$bg_colors = array('green', 'orange', 'blue', 'yellow', 'red', 'black');
//----------------------------------------
//End functions relating to wordpress

// Start PetRescue PHP/API Code
//----------------------------------------
// Open CuRL/JSON Stuff

$ch = curl_init();
$category=$_GET['category'];
$url="http://www.myapilink.com.au/api/listings?token=f716909f5d644fe3702be5c7895aa34e&group_id=10046&species=".$category;
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
'Accept: application/json',
'X-some-API-Key: f716909f5d644fe3702be5c7895aa34e',
));
$json = json_decode(curl_exec($ch), true);


// Functions relating to the Echo Code

foreach($json['listings'] as $listing)
{
$short_personality=substr($listing['personality'],0,500);
$peturl="http://mysiteurl.com.au/beta/pet-info/?petid=".$listing['id'];
$medium_photo=$listing['photos'][0]['large_340'];
$gallery_listing=$listing['photos'][5]['large_900'];
$gender_class=strtolower($listing['gender']);
$breed_class=strtolower($listing['species']);
$name=($listing['name']);
$unique_gallery_name="lightbox['.$inc.']";
    $inc++;
foreach($listing["photos"] as $photosthumb)
          {
            $photo_thumb_large=$photosthumb["large_340"];
			$photo_thumb_hidden=$photosthumb["small_80"];
		  }
$rand_background = $bg_colors[array_rand($bg_colors)];
	
// General IF/AND/ELSE Statements to refine the Echo Output
if($listing['photos'] == null) {
	$medium_photo="http://mysiteurl.com.au/beta/wp-content/themes/Archive/images/photo_coming_soon.png";
}
if($listing['desexed'] == "Yes") {
	$desexed="yes";
}
else {
	$desexed="no";
}
if($listing['vaccinated'] == "Yes") {
	$vaccinated="yes";
}
else {
	$vaccinated="no";
}
if($listing['wormed'] == "Yes") {
	$wormed="yes";
}
elseif($listing['wormed'] == "No") {
	$wormed="no";
}
else {
	$wormed="no";
}
if($listing['heart_worm_treated'] == "Yes") {
	$heart_worm_tested="yes";
}
elseif($listing['heart_worm_treated'] == "No") {
	$heart_worm_tested="no";
}
else {
	$heart_worm_tested="no";
}
if($listing['species'] == "Dog") {
	$adoption_enquiry_link="http://mysiteurl.com.au/beta/pre-adoption-form-dogs/?dog_name=$name";
	$hwt="list-$heart_worm_tested";
}
elseif($listing['species'] == "Cat") {
	$adoption_enquiry_link="http://mysiteurl.com.au/beta/pre-adoption-form-cats/?cat_name=$name";
	$hwt="list-hwt-hidden";
}

// Echo the output

echo'<div class="animal">
		<div class="animal-image">
<a class="size-thumbnail thickbox" rel="'.$unique_gallery_name.'" href="'.$medium_photo.'">
				<img src="'.$medium_photo.'" class="image-with-border" alt="">

					<div class="open"></div>

		<div class="animal-thumbnail hidden">

					</a>
		</div>		
<div class="animal-content">
	<div class="animal-left">
		<ul class="animal-list">
			<li class="list-sex-'.$gender_class.'">'.$listing['gender'].'</li>
			<li class="list-breed-'.$breed_class.'">'.$listing['breeds_display'].'</li>
			<li class="list-age">'.$listing['age'].'</li>
			<li class="list-fee">'.$listing['adoption_fee'].'</li>
		</ul>
	</div>
<div class="animal-right">
		<ul class="animal-list">
			<li class="list-'.$desexed.'">Desexed?</li>
			<li class="list-'.$vaccinated.'">Vaccinated?</li>
			<li class="list-'.$wormed.'">Wormed?</li>
			<li class="'.$hwt.'">Heart Worm Tested?</li>
		</ul>
</div>
<div class="animal-full">
		<ul class="animal-list">
			<li class="list-description">'.$listing['personality'].'</li>
		</ul>
</div></div>
<div class="clearer"></div>
</div>
<div class="delimiter"></div>';
// Close the CURL
}
curl_close($ch);
?>

Attached is some dummy data that represents the JSON data returned from the API.

 

As you can see in the file, the last line is where the paging details comes in.

 

Any help you guys could give would be appreciated.

 

Cheers,

 

Dave
