PHP combined with HTML code

Question

I am trying to put some php code in a code that is combined with HTML.

I have the following code:

<?php
$result = mysqli_query($db,"SELECT * FROM klassen");
while($record = mysqli_fetch_array($result)) {
echo '<div class="groepitem"><input type="radio" [IN THIS PLACE] name="groep" value="' . $record['klasNaam'] . '">' . $record['klasNaam'] . '</div>';
}
?>

On the [in this place] spot I want to put the following code:

if($_SESSION['gebruikers_klasid'] == $record['klas_id']) {
echo 'checked';
}

I have tried it multiple times but I just can't get it to work.

Try putting the conditional statement right after your while loop, while assigning a variable to it, like $checked="checked"; then echo/place the variable in the [in this place]. — Funk Forty Niner

You can concatenate a ternary operator like this:

$result = mysqli_query($db, "SELECT * FROM klassen");
while($record = mysqli_fetch_array($result)) {
    echo '<div class="groepitem"><input type="radio" ' . ($_SESSION['gebruikers_klasid'] == $record['klas_id'] ? "checked" : "") . ' name="groep" value="' . $record['klasNaam'] . '">' . $record['klasNaam'] . '</div>';
}

All in one go ;) ternaries are so nice to work with.

It does not seem to work. When I add the following code: ($_SESSION['gebruikers_klasid'] == $record['klas_id'] ? "checked": "") It wont add 'checked'. When I add: if($_SESSION['gebruikers_klasid'] == $record['klas_id']) { echo 'checked'; } it DOES add 'checked'.

@Diederiikk Did you start your session?

@Diederiikk Now it should work! Forgot to add spaces. Just copy it again and it should work

@Diederiikk What Rizier meant was, is session_start(); included inside all pages using sessions?

You can do this many different ways, but if you want cleaner html code:

<?php

$result = mysqli_query($db,"SELECT * FROM klassen");

while ($record = mysqli_fetch_array($result)) {

    if ($_SESSION['gebruikers_klasid'] == $record['klas_id']) {
        $checked = ' checked';
    } else {
        $checked = '';
    }

    echo '<div class="groepitem"><input type="radio"' . $checked . ' name="groep" value="' . $record['klasNaam'] . '">' . $record['klasNaam'] . '</div>';

}

?>

OR...

<?php

$result = mysqli_query($db,"SELECT * FROM klassen");

while ($record = mysqli_fetch_array($result)) {

    $checked = ($_SESSION['gebruikers_klasid'] == $record['klas_id']) ? ' checked' : '';

    echo '<div class="groepitem"><input type="radio"' . $checked . ' name="groep" value="' . $record['klasNaam'] . '">' . $record['klasNaam'] . '</div>';

}

?>

Another way is to exit your echo then run the conditional statement then resume your echo... eg

<?php 
$result = mysqli_query($db,"SELECT * FROM klassen");   
while($record = mysqli_fetch_array($result)) { 
    echo '<div class="groepitem"><input type="radio" '; 
   if($_SESSION['gebruikers_klasid'] == $record['klas_id']) { echo 'checked'; }
    echo ' name="groep" value="' . $record['klasNaam'] . '">' . $record['klasNaam'] . '</div>'; 
} 
?>

this should work

<?php

$result = mysqli_query($db,"SELECT * FROM klassen");

while($record = mysqli_fetch_array($result)) {
    if($_SESSION['gebruikers_klasid'] == $record['klas_id']) {
        $var = 'checked';
    }
    echo '<div class="groepitem"><input type="radio" '.$var.' name="groep" value="' . $record['klasNaam'] . '">' . $record['klasNaam'] . '</div>';
}

?>

EDIT: now session check it's inside the loop

Just like and similar to what I said ;) well interpreted.

Brett Over a year ago

That won't work; the comparison needs to be in the while loop.

Funk Forty Niner Over a year ago

@Brett Yep, that's why I said "similar" to what I said. It needs to be inside the while loop.

Funk Forty Niner Over a year ago

well interpreted, well... almost.
