Undefined array key "profile"

PHP

Good morning,

I get this error message and I don’t see where my error is in my code.

Do you have an idea ?

Your form doesn’t have an input named “profile”, so it won’t be defined.
Because you are looking for it in $_FILES you would specifically need a file type input of that name to define it.

Is this where I have to define profile?

<form action="" class="form-group mt-3" method="post">
                    <label for="">Image du Produit :</label>
                    <input type="file" class="form-control mt-3" name='images'>
                    <label for="">Code Article :</label>
                    <input type="text" class="form-control mt-3" name="code_article">
                    <label for="">Nom du Produit :</label>
                    <input type="text" class="form-control mt-3" name="nom_article">
                    <label for="">Quantite :</label>
                    <input type="text" class="form-control mt-3" name="quantite">
                    <button type="submit" class="btn btn-primary mt-3" name="ajouter">Enregistrer</button>
                </form>

Yes.

You’ll need to specify the correct enctype for your form, too.

Thank you for your help, in fact several of us are following an online tutorial and we are just starting out and we have this error.

I have understood the error, but from a practical code point of view, what should I do?

comme ceci je pense ?

<form action="index.php" class="form-group mt-3" method="POST" enctype="multipart/form-data" >
                <label for="">Image du Produit :</label>
                     <input type="file" class="form-control mt-3" name="profile" accept="*/image">
                   <label for="">Code Article :</label>
                   <input type="text" class="form-control mt-3" name="code_article" required>
                   <label for="">Designation du Produit :</label>
                   <input type="text" class="form-control mt-3" name="nom_article" required>
                   <label for="">Quantite :</label>
                   <input type="text" class="form-control mt-3" name="quantite" required>
                   <button type="submit" class="btn btn-primary mt-3" name="ajouter">Enregistrer</button>
               </form>

It seems to me that you’ve fixed the original problem - you now have a form field called “profile”, so the error messages should have gone away as long as you upload an image. Obviously you’ll need to check that before trying to work with it, and presumably your tutorial will cover that at some point.

You’ve also added the enctype parameter, so all should be good. Or do you still have a problem?

I have the same problem again: product_image is not defined or should I declare product_image?

The current error is when you are fetching the data from the SELECT … query. What is the column name in your database table for the image filename?

in fact I made a mistake in my database

General rule - if you want to use a variable, it needs to be defined. If there’s a chance it won’t be defined, your code needs to deal with that chance by checking whether it exists before using it.

One of the disadvantages of doing a select * query is that things like this can happen. If you’d been selecting only the columns that you are going to use, your query would confirm the list of column names right there a few lines above the code that uses them. Your query would fail before your PHP code, and you’d find that out when you tested the query in phpmyadmin.

I want to throw in here, be sure to always check if defined:

if(!empty($_REQUEST['foobar'])) {
     $foobar = htmlspecialcahrs(strip_tags($_REQUEST['foobar']));
} else {
     echo 'Sorry, that was not the droid I was looking for.';
     exit;
}
