$_post Inside A Loop

i have 5 textboxes with the name of textbox1,textbox2 ... textbox5. now what i want is that instead of putting each of their value in a variable individually I want to do it in a l

Solution 1:

This is incorrect:

$sasa = $_POST["textbox".[$i].""];  
                             ^^^^

[$i] defines a new array with a single integer in it, which you then concatenate into a string. Arrays used in a string context simply become the literal word Array, which means you're effectively running this:

$sasa = $_POST["textboxArray"];  

which doesn't exist in your form.

You want

$sasa = $_POST["textbox{$i}"];  

instead. Note the {}.

And note that your code is vulnerable to sql injection attacks.

Solution 2:

The problem is this line: $sasa = $_POST["textbox".[$i].""];

You should do it as follows:

if(isset($_POST['submit'])){

    if(is_array($_POST["textbox"])){
        foreach($_POST["textbox"] as$sasa){
            //This is unsafe, use prepared statements instead$sql="INSERT into sasa (sasa) values('$sasa')";
            $q=$conn->query($sql);
        }
    }

}

This allows you to write your form like:

<form method="post" ... >

    <inputtype="text" name="textbox[]"/>
    <inputtype="text" name="textbox[]"/>
    <inputtype="text" name="textbox[]"/>

    <button type="submit">Submit</button>

</form>

In answer to your comment, this is how you could add/remove inputs dinamically using jQuery:

var control = $('<divclass="controls"></div>');
control.append("<inputclass='form-control'type='text'name='textbox[]'placeholder='textbox'/><ahref='#'class='remove_this btn btn-danger'>remove</a>");
control.appendTo('form');

control.find('.remove_this').click(function(){
    control.remove();
});
