foreach loop with if statements

Hi,

I'm trying to establish an if statement within a foreach loop, which the output it to have the $value['name'] to be called out inbetween the HTML. But now it only provides me with 1 and the value within the value: My associative array as follows:

$options_format = [] []

    'name' => 'Audio',
    'type' => 'Audio',

];

$options_format = [] [

    'name' => 'EBook',
    'type' => 'EBook',
];

$options_format = [] [

    'name' => 'Hardcover',
    'type' => 'Hardcover',
];

$options_format = [] [

    'name' => 'Paperback',
    'type' => 'Paperback',
];

<optgroup label="Books">
                        <?php // replace back here
                            foreach ($options_format as $key => $value) {
                             echo '<option value="' . $value['name'] . '"' . '(' . $value['name'] && $value['name'].  '==' . $value['name'] . ')' . 'echo selected; }' . '"' . '>' ; 
                               echo  $value['name'];
                               echo '</option>'. "\n";
                            }
                        ?>
                        </optgroup>

the output after the loop is executed:

<optgroup label="Books">
                        1Audio</option>
1EBook</option>
1Hardcover</option>
1Paperback</option>

Any help would be appreciated, thanks.

I am finding a little hard to understand on the little parts of the checking with == yet, I think, you can get some direction from the below

<?php

$options_format = array
  (
  array('name' => 'Hardcover'
        'type' => 'Hardcover'),
  array('name' => 'Paperback',
        'type' => 'Paperback'),
  array('name' => 'EBook',
        'type' => 'EBook'),
  array('name' => 'Audio',
        'type' => 'Audio')

  );

//echo "<pre>";
//print_r($options_format);
//echo "</pre>";

echo "<select>";
  echo "<optgroup label=\"Books\">";
    foreach ($options_format as $option){
        foreach($option as $key => $value){
        echo "<option value= ".$value['name'] .">$value</option>";
        }
    }
  echo "</optgroup>";
echo "</select>";


?>

Hi Antonio,

I’m trying to a conditional so if the value is equal to the selection then it would be selected. It’s to do with form input.

Originally I was using a different variable to if $format to hold the value and compare it.

I get now, however, I would like to know, what are you trying to check against what

you say if the value is equal to the selection

where the value coming from and what is the selection

selection will be coming from another variable from within the same page, so $format will hold the variable against $value and will do the comparison.

will this be helpful

<?php

$options_format = array
  (
  array('name' => 'Hardcover',
        'type' => 'Hardcover'),
  array('name' => 'Paperback',
        'type' => 'Paperback'),
  array('name' => 'EBook',
        'type' => 'EBook'),
  array('name' => 'Audio',
        'type' => 'Audio')

  );


$format = "A";

echo "<select>";
  echo "<optgroup label=\"Books\">";
    foreach ($options_format as $option){
        foreach($option as $key => $value){
            echo "<option value= ". $value . " <?php echo $format == \"A\" ? \"selected\"=\"selected\" : ''; ?>{$value}</option>";
        }
    }
  echo "</optgroup>";
echo "</select>";

?>

this finally worked, used a ternary operator: this outputs the correct format and also has the selected attribute :)

foreach ($options_format as $key => $value) {
       echo '<option value="' . $value['name'] . '"' . ((isset($format) && $format == $value['name']) ? "$select" : "");
       echo ">" . $value['name'];
       echo '</option>' . "\n";
 }

Thanks very much for the help also.
