如何使用if语句设置数组

Question

So I have a program that is meant to output a message based on their form input on the previous page which I have grabbed with $_GET on the next page with php.

If believe it is something to do with setting the array with an if else statement.

Here is my php and JavaScript code :

<?php 
    session_start();
    $theirname = $_GET['theirname'];
    $yourname = $_GET['yourname'];
    $slct2 = $_GET['slct2'];
    $slct1 = $_GET['slct1'];
?>

<script type="text/javascript">
    var theirName = "<?php echo $theirname; ?>";
    var yourName = "<?php echo $yourname; ?>";
    var cardType = "<?php echo $slct1; ?>";
    var personType = "<?php echo $slct2; ?>";

    var myArray=[

"i need", 
"to make the contents of ",  
"this array",  
"conditional",  
"to the variable",  
"cardType",  
"and the variable",  
"personType", 


];

 //shuffle array:
myArray.sort(function(){return Math.round(Math.random());});

//print to screen
function printGreet()
{
document.getElementById('demo').innerHTML= [myArray.pop()];
}
</script>

And html:

    <button onclick="printGreet()" class="large-btn" id="generate-Btn" rows="20">Generate</button>
</div>
<div id="yourMes">
    <p>Your message:</p>
</div>
<textarea name="text1" class="large-fld" id="demo"> </textarea>

Can you give what kind of value $_GET['slct2'] contain? As you are doing json_encode in php to $slct2 variable then you need to do json decode for cardType in javascript.

Use json_encode in php, if your data is a array format or string with characters.

For json decode check http://www.w3schools.com/json/json_eval.asp.
