How can I check the database table for specific node entries by date before inserting a new node?

I want to check the node table for any node with the current date, if found, I want to delete the old one and insert a new node.

How can I achieve this.


This should do the trick:

Make a module and insert following code, switch "foo" with your module name.

    * Implements hook_node_presave($node).
    function foo_node_presave($node) {
      // Lets search for nodes on the current date.
      $somedate = strtotime(date('Y-m-d'));

      $query = new EntityFieldQuery();
      $query->entityCondition('entity_type', 'node');
      $query->propertyCondition('created', $somedate, '>=');
      $query->propertyCondition('created', $somedate + (60 * 60 * 24), '<');
      $result = $query->execute();

      if (!empty($result)) {

Obviously you might want to do some additional checks before deleting the nodes:

// Nodes of the same type
$query->propertyCondition('type', $node->type);

//Only delete published nodes
$query->propertyCondition('status', 1);
  • Thank you. It works. Please let me know how to get the date from the node form field instead of taking current date. – rongok Sep 3 '12 at 10:23
  • You can access the date using the $node variable. Just do a print_r($node) or dpm($node) to see its contents, then convert the date value to a Unix timestamp. – Bart Sep 3 '12 at 10:27
  • Thanks again for the suggestion. Is there any hook which run when click on save/submit the node. – rongok Sep 3 '12 at 11:05
  • @rongok Please open a new question if you have a different question. – Letharion Sep 3 '12 at 12:34
