php mysql多个if语句

标签： php mysql arrays if-statement

所以我有这个结果数组，我需要运行一个IF语句然后显示数据，具体取决于它是否为yes，我得到了那个部分，现在我需要在另一个中添加另一个IF语句..这是我想要做的一个例子，我知道它错了所以请帮忙。

if (isset($result_array)) {
    foreach ($result_array as $result) {
        if($result['hasChildren']=="yes") { ?>
            <center>
                <table class='kitTable' width='98%' border='1' cellpadding='2' cellspacing='0' bordercolor='556587'>
                    <tr>
                        <td width='70%' class='kitHeading'><?php echo $result['kitHeading'];?></td>
                        <td width='15%' class='kitHeading'><?php echo $result['partHeading'];?></td>
                        <td width='15%' class='kitHeading'><?php echo $result['qtyHeading'];?></td>
                    </tr>
                    <tr>
                        <td><?php echo $result['kitPart1'];?></td>
                        <td class='trCenter'><?php echo $result['childPart1'];?></td>
                        <td class='trCenter'><?php echo $result['childPartQTY1'];?></td>
                    </tr>

                    <?php if($result['kitPart2']=== NULL) { ?>
                        <tr>
                            <td><?php echo $result['kitPart2'];?></td>
                            <td class='trCenter'><?php echo $result['childPart2'];?></td>
                            <td class='trCenter'><?php echo $result['childPartQTY2'];?></td>
                        </tr>
                    <?php } ?>
                </table>
            </center>
            <?php
        }
        elseif($result['hasChildren']=="no") {
            echo "";
        }               
    }
}

我确实发现了一些错误......

  

元素“table”上不允许使用属性“bordercolor”....你需要使用CSS。

答案 1 :(得分：0)

您的表格未正确规范化。你真的需要两张桌子。

table `Parts`

partid
function
name
stocktype
image
vendor
notes
oemproj

table `children`

partid (joined to partid in parts table)
parentpartid (this is the parts table partid of the kit)
quantity

假设所有这些部分已存在于另一个表中，children中不需要任何其他数据。现在，您可以在套件中使用1到1亿个子零件，而不会使零件表膨胀。

现在你的代码更像是这样：

if (isset($result_array)) {
    foreach ($result_array as $result) {
        $id = $result['id'];
        //now query the children table for child parts (this assumes $con is your db connection
        $stmt = $con->prepare("SELECT * FROM `Children` WHERE `parentpartid` = :partid");
        $stmt->bindParam(':partid', $id, PDO::PARAM_INT);
        $stmt->execute;
        if($children = $stmt->fetchAll()) { ?>
            <center>
                <table class='kitTable' width='98%' border='1' cellpadding='2' cellspacing='0' bordercolor='556587'>
                    <tr>
                        <td width='70%' class='kitHeading'><?php echo $result['kitHeading'];?></td>
                        <td width='15%' class='kitHeading'><?php echo $result['partHeading'];?></td>
                        <td width='15%' class='kitHeading'><?php echo $result['qtyHeading'];?></td>
                    </tr>
                    <?php
                    $i = 1;
                    foreach ($children as $child) { ?>
                    <tr>
                        <td>Kit part <?php echo $i ;?></td>
                        <td class='trCenter'><?php echo $child['partid'];?></td>
                        <td class='trCenter'><?php echo $child['quantity'];?></td>
                    </tr>
                    <?php
                        $i++;
                    } ?>
                </table>
            </center>
            <?php
        }             
    }
}

这应该指向正确的方向。你可能需要做一些调整才能得到你想要的东西。如果要输出有关子部件的更多详细信息，可以运行更复杂的查询，并通过加入partid从部件表中获取部件名称等。这可能会解决您当前的问题，但更重要的是，它将通过标准化设计为您提供更多的未来灵活性。
