Finally my module code looks as below. I am trying to make use of AHAH ("Add More Companies..." button), to add next row containing company name, start date and end date fields. On clicking "Add More Companies..." button, I am getting a dialog and says *Error occured*. Please suggest me, where I am going wrong. <?php function submitresume_menu() { $items = array(); $items['submitresume/form'] = array( 'title' => t('Submit Your Resume'), 'page callback' => 'submitresume_form', 'access arguments' => array('access content'), 'description' => t('Submit Your Resume'), 'type' => MENU_CALLBACK, ); $items['submitresume/form/morecompanies'] = array( 'page callback' => 'submitresume_my_form_add_more_companies', 'access arguments' => array('access content'), 'type' => MENU_CALLBACK, ); return $items; } function submitresume_form() { return drupal_get_form('submitresume_my_form'); } function submitresume_my_form($form_state) { $form = array('#cache' => TRUE,); if (isset($form_state['all_companies'])) { $all_companies = $form_state['all_companies']; } else { $all_companies = 1; } $form['name'] = array( '#type' => 'fieldset', '#title' => t('Personal Information'), '#collapsible' => TRUE, '#collapsed' => FALSE, ); $form['name']['persname'] = array( '#type' => 'textfield', '#title' => t('Name'), '#required' => TRUE, '#description' => "Please enter your name.", '#size' => 20, '#maxlength' => 20, ); $form['name']['email'] = array( '#type' => 'textfield', '#title' => t('Email ID'), '#required' => TRUE, '#description' => "Please enter your valid email-id.", '#size' => 20, '#maxlength' => 20, ); $form['name']['mobile'] = array( '#type' => 'textfield', '#title' => t('Mobile Number'), '#required' => TRUE, '#description' => "Please enter your valid mobile number.", '#size' => 20, '#maxlength' => 20, ); $form['name']['birthdate'] = array( '#type' => 'textfield', '#title' => t('Date of Birth'), '#required' => TRUE, '#description' => "Please enter your date of birth in DD/MM/YYYY format.", '#size' => 20, '#maxlength' => 20, ); $form['work'] = array( '#type' => 'fieldset', '#title' => t('Work Information'), '#collapsible' => TRUE, '#collapsed' => FALSE, ); $form['work']['yearsexp'] = array( '#type' => 'textfield', '#title' => t('Years of Experience'), '#description' => "Please enter your years of experience.", '#size' => 20, '#maxlength' => 20, ); $form['work']['dlocation'] = array( '#type' => 'textfield', '#title' => t('Preferred work location'), '#description' => "Please enter your preferred work location.", '#size' => 20, '#maxlength' => 20, ); $form['resume'] = array( '#type' => 'file', '#title' => "Upload Resume", '#description' => 'Browse and select your resume', '#required' => TRUE, ); //////////////////////////////////////////////////////////////// for ($delta = 0; $delta < $all_companies; $delta++) { //Add a wrapper for the companies and add more button. $form['work_history_wrapper'] = array( '#title' => t("Work history: Mention all the companies you gave worked so far"), '#type' => 'fieldset', '#collapsible' => TRUE, '#collapsed' => FALSE, '#prefix' => '<div class="clear-block" id="work-history-wrapper">', '#suffix' => '</div>', ); //Container for just companies $form['work_history_wrapper']['allcompanies'] = array( '#prefix' => '<div id="all-companies">', '#suffix' => '</div>', ); $form['work_history_wrapper']['allcompanies']['company'] = array( '#type' => 'textfield', '#title' => t('Company'), '#size' => 30, '#maxlength' => 100, ); $form['work_history_wrapper']['allcompanies']['sdate'] = array( '#type' => 'date', '#title' => t('Start Date'), ); $form['work_history_wrapper']['allcompanies']['edate'] = array( '#type' => 'date', '#title' => t('End Date'), ); } $form['work_history_wrapper']['morecompany'] = array( '#type' => 'submit', '#value' => t('Add More Companies...'), '#weight' => 1, //'#submit' => array('add_more_companies_submit'), // If no javascript action.

Hi I am making a custom form, where I want to have work history of a person in one line and at the end of line a button "add more". It will look some thing like as below -

*Company * *Start-Date* *End-Date* *Add More ...* ** If user clicks on button "*Add More ...*" then it should add one more line and my form should look as below

*Company * *Start-Date* *End-Date* *Add More ...* *Company * *Start-Date* *End-Date* *Add More ...*

So how many times user clicks "*Add More ...*", those many rows should be shown up.

How can I acheive it in Drupal. As per documentation and google search AHAH is capable of doing it. Please correct me if wrong.

My custom form code is as below. My questions are -

1. How can I add 4 fields in one line. By default these are coming below of earlier field. 2. How to make use of AHAH. 3. Also one more challenge for me is how do act on "onClick" of "*Add More ...*" button, by default it may call submit handler.

A step by step approach will help me, as first time I am looking at AHAH.

Best Regards Austin
