broken image handling

I want to show a default image if there isn't any record on the table of images. I am using this one, but it shows nothing when the db's table is empty.

<img class="image--cover" id="blah" src="<?php echo $row2['img_local']; ?>" alt="Avatar" title="DEFINIDA" onerror="this.onerror=null;this.src='1.png';">

Actually, it doesn't even shows some broken image icon, not even the allocated space for this element. Any thoughts?

Edit: this is the "upload.php" code that i am using to upload the images

    <?php
session_start();
    include('includes/conexao.php');
    $fileinfo=PATHINFO($_FILES["image"]["name"]);
    $newFilename=$fileinfo['filename'] ."_". time() . "." . $fileinfo['extension'];
    move_uploaded_file($_FILES["image"]["tmp_name"],"images/perfis/" . $newFilename);
    $location="images/perfis/" . $newFilename;


$todas_fotos = mysqli_query($conexao, "select * FROM esc_usuarios_fotos WHERE img_usu_codigo = '" . $_SESSION['codigo'] . "'");

if( mysqli_num_rows($todas_fotos) > 0) {
        //$path=$location;
        //if(unlink($path)) echo "Deleted file ";
        mysqli_query($conexao,"UPDATE esc_usuarios_fotos SET img_local = '$location' WHERE img_usu_codigo = '" . $_SESSION['codigo'] . "'");
}
else
{
        mysqli_query($conexao,"insert into esc_usuarios_fotos (img_local, img_usu_codigo) values ('$location', '" . $_SESSION['codigo'] . "')");
};


    header('location:perfil.php');
?>

you can try

<img class="image--cover" id="blah" src="<?php if(!empty($row2['img_local'])){ echo $row2['img_local'];}else{ echo '1.png';} ?>" alt="Avatar" title="DEFINIDA" >

Also check path of 1.png.. Like images/1.png or img/1.png etc..

How to Keep image path name if no new image been uploaded , which update and upload image to the folder and sends path to the database set if no new image upload keep old image path or dnt change the the row on  Every tutorial I read suggested it’s best to store images in a folder and store the path into a database as opposed to storing images into a database. I want to allow users to store data and an image then retrieve and display the data and image, I know how to display the data but not the uploaded image.

My friend,

If you get this from HTML perspective... and put that image in one DIV, your [onerror="";] could work better.

like this example:

<div id="myContainerImg">
    <img class="image--cover" id="blah" src="<?php echo $row2['img_local']; ?>" alt="Avatar" title="DEFINIDA" onerror="putNoImage();">
</div>

<script type="text/javascript">
  function putNoImage(){
    document.getElementById('myContainerImg').innerHTML = 'no image here, or put your own img...';
  }
</script>

And, you can see it running here on CodePen.

  • did you check your style.? style may affect the element.!
  • Can you show what's echoed in <?php echo $row2['img_local']; ?>
  • i have updated the details
  • Still, nothing is loaded
  • do you check path of 1.png ? is it in root folder or in any subfolder ? also is it class="image--cover" or class="image-cover" ? if 1.png is in images folder, then it should be src="<?php if(!empty($row2['img_local'])){ echo $row2['img_local'];}else{ echo 'images/1.png';} ?>"
  • the path is correct, but i got no changes at all trying different paths
  • Nothing, it's so weird, looks like there is no difference between a wrong and correct path
  • Newbie here, how to go?
  • ALTER TABLE table_name ALTER COLUMN column_name SET DEFAULT 'images/default.png'. then add default.png in your images folder
  • But if the user removes the image, nothing is shown, cause in your code, there must be at least one record to show default.png, waht I want is to show a image if there is nothing on database
  • when user click 'remove image' button , dont delete it , instead of delete query execute update query , and set again to 'images/default.png' as a value to column
  • Nothing yet, i'm losting hope
  • You have set "images/perfis/" . $newFilename in DB. So on trying to display it, you have to specify the full path. Can you add the path on which you are seeing this page in browser or the folder structure
