I want to invisible the data, then i enter the Key to search, the data is displayed.

Hi tonythuan,

You'll need to add some PHP to the body to say "display nothing if the search field is empty"

Thank to your quick response .
Please show me clearly !
this is my form :
WHERE SQL "

<?php
$search_array = array( 'tenchinhanh');
$where = array();
foreach ( $search_array as $search ) {
  $value = JRequest::getVar($search, '' , 'post');
  if ( $value ) {
    $where[] = " $search LIKE '$value%' ";
  }
}
if ( !empty($where) ) {
  echo " WHERE ".implode(' AND ', $where);
}?>

Hi,

try to make your first code like:

    <?php
    $search_array = array( 'tenchinhanh');
    $where = array();
    foreach ( $search_array as $search ) {
      $value = JRequest::getVar($search, '' , 'post');
      if ( $value ) {
        $where[] = " $search LIKE '$value%' ";
      }
    }
    if ( !empty($where) ) {
      echo " WHERE ".implode(' AND ', $where);
    }else{
echo " WHERE primary_field='non_existing_value'";
}


?>

Thank you very much to your response.
