该函数product()用于名为 的页面products.php。如何使从该搜索返回的每个产品（耐克培训师）成为一个可点击的链接，指向一个名为的页面，并仅在s on 上product.php显示该产品信息？divproduct.php

/*
 * This function is used for products.php page,(search page)
 */
function product ()
{
    $get = mysql_query ("SELECT id, name, price, size, imgcover FROM products WHERE brand='nike'");
    if (mysql_num_rows($get) == FALSE)
        { echo " There are no products to be displayed!";}
    else
        { while ($get_row = mysql_fetch_assoc($get)){echo "<div id='productbox'><a href='product.php'>".$get_row['name'].'<br /> £'.$get_row['price']. '  UK'.$get_row['size']. '<br />' .$get_row['imgcover']. "</a></div>" ;} 
    }
}

/* The function productlayout () I am using for the product.php page and I am echoing this onto this page.  */

function productlayout ()
{
    $get = mysql_query ("SELECT id, name, price, size, buyfor, exfor, grade, brand, Basecolour,     imgcover FROM products WHERE id ='1'");
    if (mysql_num_rows($get) == FALSE)
        { echo " There are no products to be displayed!";}
    else
        { while ($get_row = mysql_fetch_assoc($get))
            { echo "<div id='layouttitle'>".$get_row['name']."</div>
                <br /> <div id='layoutprice'>£".$get_row['price']. "</div>
                <div id='layoutsize'>UK".$get_row['size']. "</div>
                <br /><div id='layoutgrade'>Condition  " .$get_row['grade']. "</div>
                <div id='layoutbrand'>" .$get_row['brand']. "</div>
                <div id='layoutbcolour'>Base Colour - " .$get_row['Basecolour']. "</div>
                <div id='givecash'>" .$get_row['buyfor']. "</div>
                <div id='giveexchange'>" .$get_row['exfor']. "</div>";
        } 
    }
}

任何帮助都会很棒，现在已经为此苦苦挣扎了一段时间！

在你的函数中传递你的搜索参数并像下面这样自定义它

  function product ($product =NULL)
 {

 if(!empty($product)){
      $get = mysql_query ("SELECT id, name, price, size, imgcover FROM products
 WHERE brand='nike' AND `name` LIKE '%".$product."%'");
 }else{
 $get = mysql_query ("SELECT id, name, price, size, imgcover FROM products 
 WHERE brand='nike'");
 }
 if (mysql_num_rows($get) == FALSE)
 { echo " There are no products to be displayed!";}
 else
 {while ($get_row = mysql_fetch_assoc($get)){echo "<div id='productbox'><a href='product.php'>".$get_row['name'].'<br /> £'.$get_row['price']. '  UK'.$get_row['size']. '<br />' .$get_row['imgcover']. "</a></div>" ;} 
 }
 }

相同if else的块和参数，productlayout ($product)并在查询中使用它

请不要mysql_*在新代码中使用函数。它们不再被维护并被正式弃用。看到红框了吗？改为了解准备好的语句，并使用PDO或MySQLi -本文将帮助您决定使用哪个。如果您选择 PDO，这里有一个很好的教程。
