SQL Query doesn't print varchar/text column

Question

I got a little problem here with my SQL query...

I debugged where the problem resides and realized that the varchar/text column seemed to stop my php function.

Here is my code:

$queryTest = mysqli_query($link, "SELECT dos_nom,dos_id FROM dossier");

while($dataTest = mysqli_fetch_assoc($queryTest)) {

if($dataTest['dos_id'] == $myparameter) {
    $toreturn.= '<option class="text-'.$dataTest['dos_id'].'" value="'.$dataTest['dos_nom'].'" selected>'.$dataTest['dos_nom'].'</option>';
            }
        }

The problem is in the value $dataTest['dos_nom']. Without which my query works (it prints the page normally), but I don't know why. With it, it doesn't work (it prints the top of the page, and nothing from/after my php function)...

To be precise, i use it in an ajax function.

Thanks in advance!

EDIT: I tried to print only 1 row from 'dos-nom', it works! But i when try to print out more than 1 row, the function stops!

My code:

$queryTest2 = mysqli_query($link, "SELECT * FROM dossier");
while($dataTest2 = mysqli_fetch_assoc($queryTest2)) 
        {                   
           $test[0] = $dataTest2['dos_nom'];
        }
if($dataTest['dos_id'] == $dos_id) 
  {
    $toreturn.= '<option class="text-'.$dataTest['dos_id'].'" >'.$test[0].'</option>';
  }

It prints only the last line this way. If i put a WHERE in the query it will stop the function, so i don't know what to do!

ANSWER:

É / À were in my database, i replaced them by E and A, problem solved!

Answer 1

try to use addslashes() function like

 addslashes($dataTest['dos_nom'])

maybe the value contains some backslash or some junk characters which may be breaking your code
