wie zu arbeiten, wählen Sie die Taste in PHP

Question

Meine Auswahltaste funktioniert nicht. Wenn ich die Auswahltaste und dann die Daten in der Textbox drücke, wo ich die Auswahltaste anschließe, funktioniert sie richtig.

PHP-Code

$qrydatabind='SELECT ecode, first_name, middle_name, last_name, father_name, mother_name, 
      number_of_dependents, dob, gender, identification_mark, marital_status, spouse_name, mobile_number, 
      email_id, adhar_id, pan_number, passport_number, tin_number, dl_number FROM USER_MASTER ORDER BY user_id DESC 
      LIMIT 1'; 
        $results= mysql_query($qrydatabind) or die(mysql_error()); 

         while($row = mysql_fetch_array($results)) { 
         echo 
      " 
       <div class='table-responsive'> 
<table border='1' style= 'background-color: #84ed86; color: #761a9b; ' >

Answer 1

Sie verpassen die <form action='' method='post'></form>. Also, wenn Sie sagen, if(isset($_POST['select_button'])) tatsächlich gibt es nichts zu überprüfen, ob ISset ohne die form und die Methode post. Versuchen Sie es hinzufügen und es sollte funktionieren:

**//php code** 

    $qrydatabind='SELECT ecode, first_name, middle_name, last_name, father_name, mother_name, 
       number_of_dependents, dob, gender, identification_mark, marital_status, spouse_name, mobile_number, 
       email_id, adhar_id, pan_number, passport_number, tin_number, dl_number FROM USER_MASTER ORDER BY user_id DESC 
       LIMIT 1'; 
$results= mysql_query($qrydatabind) or die(mysql_error()); 

while($row = mysql_fetch_array($results)) { 
     echo 
     " 
<div class='table-responsive'> 
    <form action='' method='post'> 
      <table border='1' style= 'background-color: #84ed86; color: #761a9b; ' > 
      <thead> 
       <tr> 
       <th></th> 
        <th>Entity Code</th> 
        <th>User Id</th> <th>User Name</th> <th>Father Name</th> <th>Mother Name</th> <th>No.Of Dependents</th> 
        <th>D.O.B</th> <th>GENDER</th> <th>Id Mark</th> <th>MARITAL STATUS</th> <th>SPOUSE NAME</th> 
        <th>Mob. Number</th> <th>E-Id</th> <th>ADHAR-ID</th> <th>PAN-No.</th> <th>PASSPORT-No.</th> 
        <th>TIN-NO.</th> <th>DL-No.</th> 
       </tr> 
        </thead> 

       <tr>   

          <td><button type='submit' class='btn btn-primary' name='select_button'>Select</button> </td> 
          <td>{$row['ecode']}</td> <td> echo $row[0];</td> 
          <td>{$row['first_name']} {$row['middle_name']} {$row['last_name']}</td>    
          <td>{$row['father_name']}</td> <td>{$row['mother_name']}</td> 
          <td>{$row['number_of_dependents']}</td> <td>{$row['dob']}</td> 
          <td>{$row['gender']}</td> <td>{$row['identification_mark']}</td> 
          <td>{$row['marital_status']}</td> <td>{$row['spouse_name']}</td> 
          <td>{$row['mobile_number']}</td> <td>{$row['email_id']}</td> 
          <td>{$row['adhar_id']}</td> <td>{$row['pan_number']}</td> 
          <td>{$row['passport_number']}</td> <td>{$row['tin_number']}</td> 
          <td>{$row['dl_number']}</td> 


       </tr> </table> 
        </form></div>"; 
      }} 

      if(isset($_POST['select_button'])) 
       { 
       $qrydatabind1='SELECT ecode, first_name, middle_name, last_name, father_name, mother_name, 
       number_of_dependents, dob, gender, identification_mark, marital_status, spouse_name, mobile_number, 
       email_id, adhar_id, pan_number, passport_number, tin_number, dl_number FROM USER_MASTER'; 
         $results1= mysql_query($qrydatabind1) or die(mysql_error()); 

          while($row = mysql_fetch_array($results1)) { 
           echo' 
          <tr >     
          <td> </td> 

          <td><input type="text" value="{$row["first_name"]}" ></td> 



       </tr>'; 

       } 
       } 

Wenn Sie ein Formular zu tun haben, und die Taste ist außerhalb davon, ich glaube, in diesem Fall javascript Sie es einreichen helfen. Angenommen, Sie haben wie dieses:

<form action='' method='post' id='form_id'> 
    <!--your inputs--> 
</form> 
<button type='submit' class='btn btn-primary' name='select_button'>Select</button> 

dann in JS Sie verwenden können:

var form = document.getElementById("form_id"); 
document.getElementsByClassName("btn").addEventListener("click", function() { 
    form.submit(); 
});
