我试图让按钮每行回显5次,并且对于每一行,它们将被一个元素包裹。
我遇到的问题是在回声时,回声没有发生我的想法。
所需结果(每5 span_1_of_5
)包裹<div class="section group"></div>
<div class="section group">
<div class="col span_1_of_5">
<div class='button_epos_a button_epos_a-border'>

PHP
$itemCount = 0;
while ($row5x = mysql_fetch_array($result5x)) {
$item_id = $row5x[item_id];
$item_title = $row5x[item_title];
if ($itemCount==0 || $itemCount%5===0) { echo "<div class='section group'>"; }
?>
<div class="col span_1_of_5">
<div class='button_epos_a button_epos_a-border'>
<div class='button_epos_a_content'>
<? echo $item_title; ?>
</div>
</div>
</div>
<?
if ($itemCount%5===0) { echo "</div>"; }
$itemCount++;
}
?>
PHP的输出(不是所需的结果)

我不明白为什么会这样,任何启蒙都会很棒。感谢
答案 0 :(得分:3)
变化:
if ($itemCount==0 || $itemCount%5===0) { echo "<div class='section group'>"; }
要:
if ($itemCount==0) { echo "<div class='section group'>"; }
同样改变:
<?
if ($itemCount%5===0) { echo "</div>"; }
$itemCount++;
}
?>
要:
<?php
if ($itemCount===4) { echo "</div>"; $itemCount = 0;} else { $itemCount++;}
}
if ($itemCount !== 0) { echo '</div>';}
?>
我认为这会让事情变得更容易。几个旁注:
<?php
代替短代码<?
。$row5x['item_id'];

$itemCount = 0;

$item_id = $row5x[item_id];
$item_title = $row5x[item_title];
if ($itemCount==0 || $itemCount==5) { echo "<div class='section group'>"; }
?>
<div class="col span_1_of_5">
