Passing JSON to Array in PHP - php

Question

I'm working on a filter in which results are filtered right away, I'm wondering if that may be the cause of the problem so I thought I would ask and see if anyone could give me a pointer on how to proceed.
<script>
var services = [
<?php
//Variables for connecting to your database.
//These variable values come from your hosting account.
$hostname = "###";
$username = "###";
$dbname = "###";
//These variable values need to be changed by you before deploying
$password = "###";
$usertable = "###";
$url = "permalink";
$title = "Address";
$amount = "rent";
$id = "id";
$status = "Beds";
$nonprofit = "Address";
//Connecting to your database
mysql_connect($hostname, $username, $password) OR DIE ("He's dead Jim");
mysql_select_db($dbname);
//Fetching from your database table.
$query = "SELECT * FROM $usertable";
$result = mysql_query($query);
if ($result) {
while($row = mysql_fetch_array($result)) {
$url = $row["$url"];
$title = $row["$title"];
$amount = $row["$amount"];
$id = $row["$id"];
$status = $row["$status"];
$nonprofit = $row["$nonprofit"];
echo '{"permalink": "';
echo "{$url}";
echo '",';
echo '"title": "';
echo "{$title}";
echo '",';
echo '"amount":';
echo "{$amount}";
echo ',';
echo '"id": "';
echo "{$id}";
echo '",';
echo '"status": "';
echo "{$status}";
echo '",';
echo '"address": "';
echo "{$address}";
echo '",';
echo '},';
}
}
?>
]
//]]>
</script>
<script id="template" type="text/html">
<a title="{{title}}" href="{{permalink}}">
<div class="fs_box hide-for-small-down">
<div class="fs_left">
<span class="fs_head">{{title}}</span>
<span class="fs_id"><img src="images/{{id}}.jpg" width="75%" height="75%" onError="this.onerror=null;this.src='images/logo.png';"></span>
<span class="fs_status">{{status}}</span>
<span class="fs_disc">{{address}}</span>
</div>
<div class="fs_price">${{amount}}+</div>
<div class="clear"></div>
</div>
</a>
</script>
I'm expecting it to produce a bunch of results that then are filtered criteria which are elsewhere in the page.
When I try it currently just as a php code it outputs fine. However, when I try it in the php file that this should go in it produces nothing. Or does it dislike being in a script?
Thanks for any help!

Answer 1

You can use json_decode and json_encode to turn an array to json and json back to an array.
Also someone will probably mention that you should not be using the mysql_* functions in PHP as they are depreciated.
Something like this:
<?php
//Variables for connecting to your database.
//These variable values come from your hosting account.
$hostname = "###";
$username = "###";
$dbname = "###";
//These variable values need to be changed by you before deploying
$password = "###";
$usertable = "###";
$url = "permalink";
$title = "Address";
$amount = "rent";
$id = "id";
$status = "Beds";
$nonprofit = "Address";
//Connecting to your database
mysql_connect($hostname, $username, $password) OR DIE ("He's dead Jim");
mysql_select_db($dbname);
//Fetching from your database table.
$query = "SELECT * FROM $usertable";
$result = mysql_query($query);
if ($result) {
$results = array()
while($row = mysql_fetch_array($result)) {
$results[] = $row;
}
$json = json_encode($results);
}
?>
]
<script>
var services = <?php echo $json; ?>;
</script>
This would give you a json object to use to render in your script.

What extension is the file you are saving?
If it's not .php or an extension set to render php, then you'll just have the code show up as test.
You might want to pull out the "die" statement after the db connect. This looks like you are running php in a .js file so you probably want the entire file to write out rather than stop because you couldn't connect to the database (or at least give 0 results, maybe a warning)
