 Posted: Fri Jul 20, 2018 11:07 am Post subject: Odd problem with Smarty template - Get data from server. |
 |
|
Hello. Im developing a website where I have a google map.
What i have so far (working).
I have a google map with various icons. If I click on an icon, it sends data to a PHP script.
- the php script accesses a database & extracts more data.
- this data is in the form of an array & i CAN use PHP "echo" to display the information inside a 2nd DIV in my template.
This is going ok & i am able to display what i want.
PROBLEM: The data / output is created within the PHP script & not via the usual Smarty template.
QUESTION: Is there a way using the Smarty template, that I can activate the PHP via clicking on the Google map icon - & create a new array.
Then re-load / refresh JUST the specified DIV but replacing Smarty with the new array data ?
I can do this by refreshing the WHOLE page, but the way it is now, I only refresh the div with new information. The rest of the page does not refresh. |

You do't need Smarty to send AJAX reply. |
Sending / Requesting the Ajax query is OK. The problem is - How do i REPLACE the results in my template with the new data ?
If my div has $array.name and it has "jones".
i press a button & it activates the script - the new value is "Peter". How do i refresh the DIV to load the NEW data.
DIV 1 - Press button. It reloads/refreshes the data in DIV2.
(the rest of the page DOES NOT refresh).
DIV2 shows the results.
IF i want to edit the presentation/display of the results now - I have to go to the PHP script & find the echo commands & change the presentation there. I cant simply edit the Smarty template to change the layout. |

After much research / googling - Ive found the answer.
When using a 2nd template, it does not automatically use the same SMARTY class as the main script.
Ive added these lines to the end of my 2nd / mini PHP script:
| Code: |
require_once ('PATH/usr/smarty3/libs/Smarty.class.php');
require_once ('../includes/Templates.inc.php');
$template_data['directory_data']=$data;
Process_Template ("directory/directory_data.tpl",$template_data);
|
(ive got a 'directory' subdirectory under my usual Smarty template path) |

I havent heard of that before now..
- So far ive only edited / changed smarty templates. Ive not altered the main Smarty class or added any new functions.
(found a few forums on autoloading & it appears its some additional class or something for PHP Smarty).
Though this thing i needed it for is probably a one-off thing, I'll not need it for anything else (I think). but my technique above does work... |
