menu - How do i get the data?(Drupal 6.x) -

i have form accepts user’s input. is, base on user input, i’d retrieve data , display user.

so far, have implemented hook_menu , registered respective url of form, , implemented submit function referred “#submit” attribute of submit button. i’ve implemented data retrieval code , works great.

here’s problem – don’t know how display retrieved data. i’ve tried several approaches in attempt find solution.

first, theme function, hoping printing return value of display data. second, setting “#action” element of form array newly registered url, thought using same url form cause drupal return form instead , not data. so, creates static variable , stores retrieved data in it;this done inside submit function way. when checked variable inside menu callback, variable not set.

to summarize problem, form has different access url form submit, such as

form url – http://....?q=mymodule/form submit url (value of ”#action”) – http://....?q=mymodule/execute 

, , data i’ve set inside submit function static variable not available in menu callback. how make data available?

here’s part of code -

static $retrieved_data;  function mymodule_menu() {    $command = array();     $command['mymodule/form'] = array(       'title' => 'user input',       'page callback' => 'response',       'page arguments' => array('form'),       'access arguments' => array('access content'),       'type' => menu_callback,    );     $command['mymodule/execute'] = array(       'title' => 'search',       'page callback' => 'response',       'page arguments' => array('execute'),       'access arguments' => array('access content'),       'type' => menu_callback,    );     return $command; }  function _response($parequest){     switch($parequest){       case "form":          return drupal_get_form("_myform");       break;        case "execute":          return $retrieved_data;       break;    } }  function _myform(&$form_state) {    $form['#action'] = url($base_path)."?mymodule/execute";    .....    $form['submit'] = array(       '#type' => 'submit',       '#value' => t('submit'),       '#submit' => array('_data_retrieve'),        );    return $form;  }  function _data_retrieve($form, &$form_state){    /*data retrieval code*/    ........................    $retrieved_data = db_fetch_object($result); } 

thanks bunch

your method seems bit complicated there. when make systems form, tend way. in mymodule_menu() change 'page arguments' => array('form'), 'page arguments' => array('name_of_form_function'), name_of_form_function _myform in case. rename mymodule_myformname.

then create function:

mymodule_myformname_submit($form, &$state) {     // enter code here save data form stored in $state     // database sql query or node_save($node) if      // creating node. } 

after can retrieve data database in _data_retrieve function , call on page want retrieve data.
