Question

A guy did some php/database work for me a while back. He linked the pages to a menu (which had a separate function/table). I’m a little lost on how it’s beneficial to link everything to a menu like that.

Here’s the code I’m trying to figure out:

function writeContent($page){
$parentQ = "select * from cdi_content where page=\"$page\"";//query to obtain content for this page
$parentResult = mysql_query($parentQ);//run query
$link = mysql_fetch_assoc($parentResult);//result
echo $link['content'];//write content`
}

With <?php writeContent("DDesign/index.php");?> on the index.php page he created.

From what I understand it runs through the menu function, but I’m just trying to get it to print what’s in the “content” field in the database.

Answer 1

First check how many number of rows are there in the query. Replace that piece if code with this.

function writeContent($page){
    $parentQ = "select * from cdi_content where page=\"$page\"";//query to obtain content for this page
    $parentResult = mysql_query($parentQ);//run query
    $total = mysql_num_rows($parentResult);

    if($total > 1) {

        while($rows = mysql_fetch_array($parentResult) {

            echo "Content: ".$row['content'] . "<br/>";
        }

    }else{

            $rows = mysql_fetch_assoc($parentResult);//result
            echo $rows['content'];//write content`

    }

}
