撇号[']不保存在数据库中

Values don't save in database when I use : apostrophe [ ' ]

I changed database collation to "utf8_general_ci" & column type to BLOB.

addslashes :

<td <?php if($userdepart==0 ) { ?>
    contenteditable="true"
    onBlur="saveToDatabase(this,'name','<?php echo addslashes($orderrecords[$k]["id"]); ?>')"
    <?php } ?>>
    <?php echo substr(addslashes($orderrecords[$k]["name"]),0,75); ?>
</td>

Also I tried mysqli_real_escape_string

<td <?php if($userdepart==0 ){?>
    contenteditable="true"
    onBlur="saveToDatabase(this,'name','<?php echo addslashes(mysqli_real_escape_string($mysqli,$orderrecords[$k]["id"])); ?>')"
    <?php }?>>
    <?php echo addslashes(mysqli_real_escape_string($mysqli,substr($orderrecords[$k]["name"],0,975))); ?>
</td> 

Right now I really can't use prepared statements and parameterized queries, as this is used by only company users. Please help me with a work around....

update

function saveToDatabase(editableObj,column,id) {

    if(column=="image_ready" || column=="ready_to_print" || column=="ready_to_packaging" || column=="ready_to_dispatch"){cvalue=editableObj;}else{var cvalue=$(editableObj).text();}

      $.ajax({
        url: "editOrder.php",
        type: "POST",
        data:'column='+column+'&editval='+cvalue+'&id='+id,
        success: function(data){
          $(editableObj).css("background","#dddddd");
          if(column=="image_ready" || column=="ready_to_print" || column=="ready_to_packaging" || column=="ready_to_dispatch"){location.reload();}
        }
      });

editOrder.php

$sql = "UPDATE do_order set " . $_POST["column"] . " = '".$_POST["editval"]."' WHERE  id=".$_POST["id"];

use prepared statements:

$stmt = $conn->prepare("INSERT INTO MyGuests (firstname, lastname, email) VALUES (?, ?, ?)");
$stmt->bind_param("sss", $firstname, $lastname, $email);
$firstname = "John";
$lastname = "D'''oe";
$email = "john@example.com";
$stmt->execute();
