How to write a plugin using wp-xajax.<\/p>\n\n
Obviusly you have to install it at first. Nothing will happen when you activate it, thats the way it is.<\/p>\n\n
Now, inside your plugin, you will write you php function that will be dinamically called through javascript.<\/p>\n\n
This function can do anything you like: access the database, send emails, call other functions.. whatever.<\/p>\n\n
The only thing this function can not do is to produce any output to the screen. It cannot have any \"echo\" calls.<\/p>\n\n
In the next step we will see how to send output to the screen. So, lets say we want a function to send an email:<\/p>\n\n
function myplugin_sendEmail(){<\/p>\n\n
$friends = 'bob@example.org,susie@example.org';\nmail($friends, \"blog updated\", \n 'I just put something on my blog: http:\/\/blog.example.com');\n<\/code><\/pre>\n\n}<\/p>\n\n
This function does not receive any argumnent, but you can have a function that receives as many argumnents as you like.<\/p>\n\n
\n- Add some response to your function<\/li>\n<\/ol>\n\n
Lets say you have a div next to your button with the id \"response_div\". Then you can add this to you function:<\/p>\n\n
function myplugin_sendEmail(){<\/p>\n\n
$friends = 'bob@example.org,susie@example.org';\nmail($friends, \"blog updated\", \n 'I just put something on my blog: http:\/\/blog.example.com');\n\n$objResponse = new xajaxResponse();\n$objResponse->addAssign(\"response_div\",\"innerHTML\",\"Email Sent!\");\nreturn $objResponse;\n<\/code><\/pre>\n\n}<\/p>\n\n
You will allways interact with the page objects using their ids. There are many ways in wich you can interact, have a look at\nthe full doc here: http:\/\/xajaxproject.org\/wiki\/Documentation:xajaxResponse.inc.php<\/p>\n\n
\n- Call your function<\/li>\n<\/ol>\n\n
A javascript function will be created. It will be called xajax_YourFunctionName.<\/p>\n\n
So you may have a button, and add to this button the event Handler:<\/p>\n\n
input type=\"button\" onclick=\"xajax_myplugin_sendEmail()\";<\/p>\n\n
if you have any arguments to pass, do it now as if it was a regular javascript function.<\/p>\n\n
\n- Register your function<\/li>\n<\/ol>\n\n
Create a function that will register your xajax_function as follow:<\/p>\n\n
function myplugin_xajax(){\ngobal $xajax;\n$xajax->registerFunction(\"myplugin_sendEmail\");\n}<\/p>\n\n
And then add an action to call it:<\/p>\n\n
add_action('init','myplugin_xajax');<\/p>\n\n
\n- Enjoy!<\/li>\n<\/ol>\n\n\n
