How to carry an array value from javascript to php?
Explanation
The javascript array values can be passed to a php file using the following method
Step 1:
Let us consider we have a js array as
<script language=javascript>
scriptAr = new Array();
scriptAr[0] = "one";
scriptAr[1] = "two";
scriptAr[2] = "three";
<script>
Step 2:
Now we will create a hidden form field as follows
<form action="phpArrayTest.php" method=post name=test onSubmit=setValue()>
<input name=arv type=hidden>
<input type=submit>
</form>
Here what we have done is, when the submit is called we first do some work ("onSubmit=setValue()")
by using the onSubmit method. The onSubmit method will invoke setValue() function defined by us.
After that the action will take place and stringTokens.php will be called.
Step 3:
Here we define the setValue method. The method will convert the array periviously defined in to a string
and then set it to the hidden field.
<script language=javascript>
function setValue()
{
var arv = scriptAr.toString(); // This line converts js array to String
document.test.arv.value=arv; // This sets the string to the hidden form field.
}
</script>
Step 4:
In the php file the string will be split back into array.
