問題描述

是他們在 while 循環中將變量分配給 div 中的類的一種方式，對于 while 循環中的每三個項目.我正在使用藍圖結構，第三個 div 在最后，我需要為每三個 div 附加一個最后一個"類名，所以 3rd div 6th div 9th div 等等?

/* 循環鞋數據表 */$results = mysql_query("SELECT * FROM shoesData");while($row = mysql_fetch_array($results)){$name = $row['name'];$about = $row['about'];$company = $row['company'];$buy = $row['buy'];$tags = $row['tags'];$id = $row['id'];$image = $row['image'];/* 回顯鞋數據結果 */echo "
";echo "<div id='imageHeight'>";echo "<img src='thumbs/$image'>";回聲</div>";echo "
";echo "
$name";echo "<li>$about</l1>";echo "<li>$company</l1>";echo "<li><a href='$buy'>BUY</a></l1>";echo "<li>$tags</l1>";echo "</ul>";回聲</div>";}/*當循環結束時鞋數據*/

for ($i = 0; $i <$numRecords; $i++){$className = "";如果 (($i % 3) == 0){$className = "last"}....}

這里的關鍵部分是($i % 3) == 0.

以下是對您的評論的回應.

/* 循環鞋數據表 */$results = mysql_query("SELECT * FROM shoesData");$i = 0;while($row = mysql_fetch_array($results)){$i++;$name = $row['name'];$about = $row['about'];$company = $row['company'];$buy = $row['buy'];$tags = $row['tags'];$id = $row['id'];$image = $row['image'];/* 回顯鞋數據結果 */$additionalClass = ($i % 3) == 0 ?"最后的" : "";echo "<div class='imageBorder span-8 column" .$additionalClass ."'>";echo "<div id='imageHeight'>";echo "<img src='thumbs/$image'>";回聲</div>";echo "
";echo "
$name";echo "<li>$about</l1>";echo "<li>$company</l1>";echo "<li><a href='$buy'>BUY</a></l1>";echo "<li>$tags</l1>";echo "</ul>";回聲</div>";}/*當循環結束時鞋數據*/

Is their a way in a while loop to assign a variable to a class in a div, for every third item in a while loop. I am using the blueprint structure and the third div is at the end and i need to attacht a "last" class name to every third div so 3rd div 6th div 9th div and so on?

/* LOOP THROUGH SHOEDATA TABLE */

$results = mysql_query("SELECT * FROM shoeData");


while($row = mysql_fetch_array($results)){

$name = $row['name'];
$about = $row['about'];
$company = $row['company'];
$buy = $row['buy'];
$tags = $row['tags'];
$id = $row['id'];
$image = $row['image'];


/* ECHO THE SHOEDATA RESULTS */     

    echo "<div class='imageBorder span-8 column'>";
        echo "<div id='imageHeight'>";
        echo "<img  src='thumbs/$image'>";
        echo "</div>";

        echo "<ul>";

            echo "<li>$name</l1>";
            echo "<li>$about</l1>";
            echo "<li>$company</l1>";
            echo "<li><a href='$buy'>BUY</a></l1>";
            echo "<li>$tags</l1>";
        echo "</ul>";
    echo "</div>";


}/*SHOEDATA WHILE LOOP ENDS */

for ($i = 0; $i < $numRecords; $i++)
{
 $className = "";
 if (($i % 3) == 0)
 {
  $className = "last"
 }

 ....
}

The key part here is the ($i % 3) == 0.

EDIT: The following is in response to your comment.

/* LOOP THROUGH SHOEDATA TABLE */

$results = mysql_query("SELECT * FROM shoeData");

$i = 0;
while($row = mysql_fetch_array($results)){
$i++;
$name = $row['name'];
$about = $row['about'];
$company = $row['company'];
$buy = $row['buy'];
$tags = $row['tags'];
$id = $row['id'];
$image = $row['image'];


/* ECHO THE SHOEDATA RESULTS */         
    $additionalClass = ($i % 3) == 0 ? " last" : "";
    echo "<div class='imageBorder span-8 column" . $additionalClass . "'>";
        echo "<div id='imageHeight'>";
        echo "<img  src='thumbs/$image'>";
        echo "</div>";

        echo "<ul>";

                echo "<li>$name</l1>";
                echo "<li>$about</l1>";
                echo "<li>$company</l1>";
                echo "<li><a href='$buy'>BUY</a></l1>";
                echo "<li>$tags</l1>";
        echo "</ul>";
    echo "</div>";


}/*SHOEDATA WHILE LOOP ENDS */
