Use only part of a GET[id] value.

[jeff5656]

Hello,

 

Lets say I have a form and I want to pre-populate a field:

Last Name:<input type="text" size="12"  name="lname" value="<?php echo $_GET['pt'];?>"/>

 

Now what if this is the patient's name and I want to only put in their last name?

Smith, Christopher

 

IS there a command to take GET['pt'] and only use all the characters UP TO the comma (and exclude the comma)?

Thanks!

Last Name:<input type="text" size="12"  name="lname" value="<?php echo substr($_GET['pt'],0,strpos($_GET['pt'],','));?>"/>

Use Split(str pattern, str string)

 

$name = "John, Doe";

$splitName = split(",",$name);

 

Now $splitName would be an array with 2 values..

 

$splitName[0] = "John"

$splitName[1] = "Doe"

 

so to get just the first name echo out $splitName[0];

 

cheers...
