How to get the $form_state in hook form submit?

Question

I need to create a node when a comment is submitted in nodes. There are two content types image and memory and I need to get node ID of the node that a user is inserting comment in it.

Here is my code

function THEME_form_submit(&$form_state, $form_id){
    if($form_id == "comment_node_memory_form" || $form_id == "comment_node_image_form"){
        kpr($form_state);
        //Insert new node 
    }
}

Clearly this code won't display the $form_state but I need to some how get the node ID and the ID of the user who inserting the comment. I guess these information are in $form_state but I really have no idea how to get them.

Thanks

If you can see it, it is not mean that your submit hook not run,
you can use dpm( it is useful dpm function in devel module ) or use something like below line in your submit or validate functions,

drupal_set_message("<pre>" . print_r($form, 1) . "</pre>");

  function THEME_form_submit(&$form_state, $form_id){
if($form_id == "comment_node_memory_form" || $form_id == "comment_node_image_form"){
drupal_set_message("<pre>" . print_r($form_state, 1) . "</pre>");
}

}

after it you sure that your function run and you can see exists variable there.

first try this, if not work try other solution(creating module ) instead THEME_form_submit(&$form_state, $form_id){ write THEME_form_submit($form, &$form_state){

update part

I suggest you put this code in your custom module

function mycmodule_form_submit(&$form,&$form_state, $form_id){
    if(in_array($form_id,array("comment_node_memory_form","comment_node_image_form"))){
           $form['actions']['submit']['#submit'][] = '_mycmodule_custom_sumbmit_handler';
        //ym($form);
       }
    }

function _mycmodule_custom_sumbmit_handler($form,&$form_state){
        /// every sumibted data provided in $form_state
        /// dsm($form_state);
       drupal_set_message("<pre>" . print_r($form_state, 1) . "</pre>");
  }

and if you not have custom module lead you to create it,

first creaate a directory(folder) name it as mycmodule

then create two file in it

• mycumodule.module
• mycumodule.info

then put this content in there

in mycumodule.module

function mycmodule_form_submit(&$form,&$form_state, $form_id){
    if(in_array($form_id,array("comment_node_memory_form","comment_node_image_form"))){
           $form['actions']['submit']['#submit'][] = '_mycmodule_custom_sumbmit_handler';
        //ym($form);
       }
    }

function _mycmodule_custom_sumbmit_handler($form,&$form_state){
        /// every sumibted data provided in $form_state
        /// dsm($form_state);
       drupal_set_message("<pre>" . print_r($form_state, 1) . "</pre>");
  }

inmycmodule.info

name = My custom module
description = custom module provide some devel changes
core = 7.x
package = My Package

If you only need nid of node comment is being inserted inside and uid of comment author then use these codes :

nid exist in : $form_state ['values']['nid']

you can even load node if you need more info about it using :

$node = node_load($form_state ['values']['nid']);

to get info about author use : $form_state ['values']['uid']

if user is anonymous this returns 0

Answer 3

Comments are an Entity in Drupal.

The comment entity object consists of the Node id on which the comment is attached. Try

MYMODULE_entity_insert($entity, $type) {

//Paste your  node creation code here

}

See https://api.drupal.org/api/drupal/modules%21system%21system.api.php/function/hook_entity_insert/7 for more details on this hook

Answer 4

/**
 * This will give you all nodes of your selected content type
 **/
    $query = new EntityFieldQuery();
    $query->entityCondition('entity_type', 'node')
          ->entityCondition('bundle', $content_type)
          ->propertyCondition('status', 1);
     $results = $query->execute();
    $node_ids = array_keys($results['node']);
/**
 * This will give you all nodes of that content type
 **/
$compfields = node_load_multiple($node_ids);

/**
 **Now check here, for each node, if it has comments, get the node id. It will check each node, and if there is any comment present, it will reflect node id.**
 **/
foreach($compfields as $keys => $node){
if($node->cid >0){
print $node->nid;
}
}

Answer 5

In that case use hook_form_alter in custom module.

Use dpm($form),check what datas it rendered first.

Store desired datas in a custom table.Then use a custom trigger (pull all stored datas from custom table)to notify users.

Answer 6

The accepted answer doesn't show how to get the ID of the node for which the comment is being posted. Given the code used to generate the comment form (comment_form()), you can use code similar to the following one, in Drupal 7.

function mymodule_form_alter(&$form, &$form_state, $form_id) {
  if ($form_id == "comment_node_memory_form" || $form_id == "comment_node_image_form") {
    if (isset($form_state['comment'])) {
      // Get the node ID from the comment object passed in $form_state.
      $nid = $form_state['comment']->nid;
    }
  }
}
