title: I have to press the submit button twice (PHP)
body: <p>This code is used to put a data in the database once the button is activated and then take it off and replace it by(Question save!). The problem is it take me two attempts to make it disappear(the button). $numofrow is used to verify if the action was once made(the action of the submit button). The problem is not the database,query,etc, its really the button. Thanks for your time.</p>
  
  <p>This is my code:</p>
  
  <pre><code>if(isset( $real_domaine)){
  
      $tt = "SELECT*FROM uniwix.table0 WHERE id= '$id' "; 
      $rr = mysqli_query($database,$tt);
  
      while($rows = mysqli_fetch_assoc($rr)){
  
          [rows call...]
  
          $md = "SELECT*FROM uniwix.table1 WHERE usern='$us' and question='$sujet'";
          $ao = mysqli_query($database,$md);
          $numofrow = mysqli_num_rows($ao);
  
          if($numofrow == 0){
              echo '&lt;form action="" method="POST"&gt;
                  &lt;input type="submit" name="sauvegarder" value="Save the question"/&gt;
                  &lt;/form&gt;';
  
              if(isset($_POST['sauvegarder'])){
                  $qu = "INSERT INTO database (usern,question) VALUES('".$us."','".$sujet."')";
                  $sm = mysqli_query($database,$qu);
              }
          }else{
              echo 'Question saved!';
          }
  
      //end of while loop
      }    
  
  // end of  if(isset( $real_domaine))
  }
  </code></pre>
