（PHP / JQuery？）选中复选框时获取表的行值

Question

It's a table, each row consists a checkbox, when it's checked, would like to get the respective td values and echo out. Here im using the if statement, but it doesn't seems to work.

And iam using php here, is using jquery a way out, can jquery work with php code, so could i send those checked table row values back to serve? Any thoughts? Thank you.

  <form>
  <table>
  <tr>
  <?php

 $specific = []; 
 while($row = mysqli_fetch_array( $result ,MYSQL_ASSOC)) {?>

 <td><input type="checkbox" name="p[]" value="<?php echo $row['id']; ?>">
 </td>

  <td><input type="text"  name="patientid[]" 
  style="border: none" value="<?php echo $row['patientid'] ?>"></td>

  <td>
  <textarea name="msg" style="border: none" class='msg'>
  <?php echo  $row['message'];} ?> </textarea>
  </td>

 <td><input class="phone" type="text" value="<?php echo 
 $row['telMobile'] ?>"></td>

check whether table row(s) are checked

  <?php if(!isset($_GET['p'])){

  $specific[] = [
                 "phone" => $row["telMobile"],
                 "message" =>$row["message"],

  ];}
  }  

  $result = json_encode($specific,JSON_UNESCAPED_UNICODE);
  echo $result; 

  echo "</tr>";
  echo "</table>";
  echo "</form>";?>

The desired result for $result is to show only the data of the table row(s) that are checked .

 [{"phone":"123456","message":"test"},
 {"phone":"789456","message":"testing"}]

Change your HTML code as below:

<td><input type="text"  name="patientid[<?php echo $row['id']; ?>]" 
  style="border: none" value="<?php echo $row['patientid'] ?>"></td>

  <td>
  <textarea name="msg[<?php echo $row['id']; ?>]" style="border: none" class='msg'>
  <?php echo  $row['message'];} ?> </textarea>
  </td>

 <td><input name="phone[<?php echo $row['id']; ?>]" class="phone" type="text" value="<?php echo 
 $row['telMobile'] ?>"></td>

I have added <?php echo $row['id']; ?> <?php echo $row['id']; ?> in the input control name.

Change your PHP code as below:

foreach($_GET["p"] as $id) {
   $specific[] = [
         "phone" => $_GET["phone"][$id],
         "message" => $_GET["msg"][$id],
       ];
}
