Form select with binary options


Recommended Posts

I have a column in my db called 'Sold' which is set to Binary. I need a dropdown in my form, that converst the binary into 'True', 'False' for the options, and also selects the one that is set in the db.

This is for an edit form, so will then need to adapt it for a add form.

This is my code, which doesnt seem to be working

        <?php
		$id = $_GET["id"];
        $sqlSold = "SELECT Sold FROM Products WHERE idProducts = $id;";
        $products = [
    		'True' => true, 
    		'False' => false
		];
		?>
     <select name="Sold">
        <option selected="selected">Choose one</option>
        <?php       
        foreach($products as $item){
            echo "<option value='strtolower($item)'>$item</option>";
        }
        ?>
    </select>

You don't execute any queries and you don't have anything in your query string that references the 'sold' column.

Nor do have a form or any form submission.

So what are you expecting it to do?

What RDBMS are you using? (If it's MySQL, boolean is stored as tinyint)

Try

$products = [
            'True' => 1, 
            'False' => 0
            ];

then

foreach($products as $txt => $val){
            echo "<option value='$val'>$txt</option>";
        }

Thanks Barand,

Sorry its so basic, Im just starting out with PHP.

To get the option to be selected accordign to the db value, i a trying the code below,and its not quite working.

        <?php
		$id = $_GET["id"];
        $sqlSold = "SELECT Sold FROM Products WHERE idProducts = $id;";
        $products = [
    		'True' => 1, 
    		'False' => 0
		];
		?>
     <select name="Sold">
        <option selected="selected">Choose one</option>
        <?php       
        foreach($products as $item => $val){
            echo "<option value='strtolower($item)' if($val == $products ? 'selected=selected' : ''')>$item</option>";
        }
        ?>
    </select>

Perhaps

<?php
    $res = $pdo->prepare("SELECT Sold FROM Products WHERE idProducts = ?");
    $res->execute([ $_GET["id"] ]);
    $sqlSold = $res->fetchColumn();

    function productOptions($current) {
        $products = [
            'True' => 1, 
            'False' => 0
        ];
        $opts .= '';
        foreach ($products as $txt => $val) {
            $sel = $val==$current ? 'selected' : '';
            $opts .= "<option value='$val' $sel>$txt</option>";
        }
        return $opts;
    }

?>

<html>
<body>
     <select name="Sold">
        <option selected="selected">Choose one</option>
        <?= productOptions($sqlSold)?>
    </select>
</body>
</html>
