Wie erhält man einen dynamischen Wert, wenn man in PHP auf die Schaltfläche klickt?

Ich habe dynamische Tasten in PHP erstellt. Ich brauche den Wert dieser Schaltfläche, wenn eine bestimmte Schaltfläche geklickt wird. Und wenn wir auf die Schaltfläche klicken, werden alle Informationen in das Formular abgerufen.Wie erhält man einen dynamischen Wert, wenn man in PHP auf die Schaltfläche klickt?

Hier ist mein Code für Button

<?php 

function dash() 
{ 
    include 'config.php'; 
    $sql = "SELECT roomno FROM roombook"; 

    if($result = mysqli_query($db, $sql)) 
    { 
      $str = ''; 

      while($row = mysqli_fetch_array($result)) 
      { 
       // generate array from comma delimited list 
       $rooms = explode(',', $row['roomno']); 

       //create the dynamic button and set the value 
       foreach ($rooms as $k=>$v) 
       { 
        $str .= '<input type="button" onClick="showDiv()" name="btn_'.$k.'" value="'.$v.'" id="btn_'.$k.'"/>'; 
       } 
      } 

      return $str; 
     } 
     else { 
      echo "ERROR: Could not able to execute $sql. " . mysqli_error($db); 
      } 

    mysqli_close($db); 
} 
?> 

<!Doctype html> 
<html> 
<head> 
    <meta charset="UTF-8"> 
    <title>room boking</title> 

    <link href="css/bootstrap1.min.css" rel="stylesheet"> 
     <link rel="stylesheet" href="css/front.css"> 

</head> 
<body> 
<form method="post" action=""> 
<div class =" row box col-md-4" > 
<div style="color:black"><?php echo dash();?></div> 
</div> 

</form>

hier den Wert in Form Code Abrufen

** ACHTUNG: ** Wenn Sie 'mysqli' verwenden, sollten Sie [parametrisierte Abfragen] (http://php.net/manual/en/mysqli.quickstart.prepared-statements.php) und [bind_param] (http://php.net/manual/en/mysqli-stmt.bind-param.php), um Benutzerdaten zu Ihrer Abfrage hinzuzufügen. Verwenden Sie NICHT die String-Interpolation oder Verkettung, um dies zu erreichen, weil Sie einen schwerwiegenden [SQL-Injektionsfehler] (http://bobby-tables.com/) erstellt haben. ** NIEMALS ** $ _POST ',' $ _GET' oder ** beliebige ** Benutzerdaten direkt in eine Abfrage einfügen, da es sehr schädlich sein kann, wenn jemand versucht, Ihren Fehler auszunutzen. – FrankerZ

Speichern Sie Ihren Wert in Daten-Attribut und holen Sie dann mit ihm – CyberAbhay

bitte erklären Sie im Detail – Yogesh

Sie können Ihre Schaltfläche wie folgt

$str .= '<input type="button" onClick="showDiv()" data-atribute-id="valueyouwant" name="btn_'.$k.'" value="'.$v.'" id="btn_'.$k.'"/>';

Script sollte wie

sein erstellen

$("button").click(function() { 
    alert(this.id); OR 
    alert($(this).attr('id')); OR 
    alert($(this).attr('data')); OR 
    var btnid = $(this).attr('data');//which give you current clicked btn id 
});

Sie können diese verwenden:

// is going to select all elements that its name start with *btn_* (your dynamic buttons) 

$('[name^="btn_"]').click(function() { 
    //get the value of the button that was clicked 
    var buttonValue = $(this).val(); 

    // send data to the other file using the action attribute of the form 
    $('form').submit(); 
});

Hoffnung, die helfen können.
