foreach循环，需要根据数组中的内容停止和启动 [英] foreach loop that requires to stop and start based on whats in a array

问题描述

我现在在我的代码中有一个循环，

 < table width =100％cellpadding = 0cellspacing =0border =0> 
<？php foreach（$ credit as $ credit）：？> 
 <？php if（$ credit ['credit_type'] ==short）：？> 
< tr> 
< td><？php echo $ credit ['category_position']; ？>< / TD> 
< td><？php echo $ credit ['category_title']; ？>< / TD> 
< / tr> 
< tr> 
< td><？php echo $ credit ['credit_heading']; ？>< / TD> 
< td>< a href =>编辑< / a>< / td> 
< / tr> 
<？php endif; ？> 
<？php if（$ credit ['credit_type'] ==long）：？> 
< tr> 
< td><？php echo $ credit ['category_position']; ？>< / TD> 
< td><？php echo $ credit ['category_title']; ？>< / TD> 
< td>< strong>标题< / strong>< / td> 
< td>< strong>角色< / strong>< / td> 
< td>< strong> Director< / strong>< / td> 
< / tr> 
< tr> 
< td><？php echo $ credit ['credit_position']; ？>< / TD> 
< td><？php echo $ credit ['credit_heading']; ？>< / TD> 
< td><？php echo $ credit ['credit_title']; ？>< / TD> 
< td><？php echo $ credit ['credit_role']; ？>< / TD> 
< td><？php echo $ credit ['credit_director']; ？>< / TD> 
< / tr> 
<？php endif; ？> 
<？php endforeach; ？> 
< / table> 
  

然而这并不是我所希望的，
$ b $我想要做的是每次 $ credit ['category_title'] 改变它的值我想开始一个新表，这是可能的吗？

新代码

 <？php foreach（$ credit as $ credit）：？> 
 <？php if（$ credit ['credit_type'] ==short）：？> 
< table width =100％cellpadding =0cellspacing =0border =0> 
< tr> 
< td><？php echo $ credit ['category_position']; ？>< / TD> 
< td><？php echo $ credit ['category_title']; ？>< / TD> 
< / tr> 
< tr> 
< td><？php echo $ credit ['credit_heading']; ？>< / TD> 
< td>< a href =>编辑< / a>< / td> 
< / tr> 
< / table> 
<？php endif; ？> 
<？php if（$ credit ['credit_type'] ==long）：？> 
< table width =100％cellpadding =0cellspacing =0border =0> 
<？php echo $ oldvalue。  变成 。 $信贷[ category_title]; ？> 
 <？php if（$ credit ['category_title']！= $ oldvalue）：？> 
< tr> 
< td><？php echo $ credit ['category_position']; ？>< / TD> 
< td><？php echo $ credit ['category_title']; ？>< / TD> 
< td>< strong>标题< / strong>< / td> 
< td>< strong>角色< / strong>< / td> 
< td>< strong> Director< / strong>< / td> 
< / tr> 
 
< tr> 
< td><？php echo $ credit ['credit_position']; ？>< / TD> 
< td><？php echo $ credit ['credit_heading']; ？>< / TD> 
< td><？php echo $ credit ['credit_title']; ？>< / TD> 
< td><？php echo $ credit ['credit_role']; ？>< / TD> 
< td><？php echo $ credit ['credit_director']; ？>< / TD> 
< / tr> 
<？php $ oldvalue = $ credit ['category_title']; ？> 
<？php endif; ？> 
< / table> 
<？php endif; ？> 
<？php endforeach; ？>

注意只有当您只有2 credit_type 值

I currently have this as a loop in my code,

    <table width="100%" cellpadding="0" cellspacing="0" border="0">
    <?php foreach($credits as $credit) : ?>
        <?php if($credit['credit_type'] == "short") : ?>
            <tr>
                <td><?php echo $credit['category_position']; ?></td>
                <td><?php echo $credit['category_title']; ?></td>
            </tr>
            <tr>
                <td><?php echo $credit['credit_heading']; ?></td>
                <td><a href="">Edit</a></td>
            </tr>
        <?php endif; ?>
        <?php if($credit['credit_type'] == "long") : ?>
            <tr>
                <td><?php echo $credit['category_position']; ?></td>
                <td><?php echo $credit['category_title']; ?></td>
                <td><strong>Title</strong></td>
                <td><strong>Role</strong></td>
                <td><strong>Director</strong></td>
            </tr>
            <tr>
                <td><?php echo $credit['credit_position']; ?></td>
                <td><?php echo $credit['credit_heading']; ?></td>
                <td><?php echo $credit['credit_title']; ?></td>
                <td><?php echo $credit['credit_role']; ?></td>
                <td><?php echo $credit['credit_director']; ?></td>
            </tr>
        <?php endif; ?>
    <?php endforeach; ?>
</table>

However this is not doing what I had hoped,

What I wanting to do is that everytime, $credit['category_title'] changes it value I want to start a new table, is this possible?

======

OK, so this has worked and I am getting a new table for every new category title, however it is not showing all the credits with that category title, for example I have to commercial credits but it is only showing one,

new code

<?php foreach($credits as $credit) : ?>
    <?php if($credit['credit_type'] == "short") : ?>
      <table width="100%" cellpadding="0" cellspacing="0" border="0">
        <tr>
            <td><?php echo $credit['category_position']; ?></td>
            <td><?php echo $credit['category_title']; ?></td>
        </tr>
        <tr>
            <td><?php echo $credit['credit_heading']; ?></td>
            <td><a href="">Edit</a></td>
        </tr>
      </table>
    <?php endif; ?>
    <?php if($credit['credit_type'] == "long") : ?>
       <table width="100%" cellpadding="0" cellspacing="0" border="0">
            <?php echo $oldvalue . " changed to ". $credit['category_title']; ?>
            <?php if($credit['category_title'] != $oldvalue) : ?>
                <tr>
                    <td><?php echo $credit['category_position']; ?></td>
                    <td><?php echo $credit['category_title']; ?></td>
                    <td><strong>Title</strong></td>
                    <td><strong>Role</strong></td>
                    <td><strong>Director</strong></td>
                </tr>

                <tr>
                    <td><?php echo $credit['credit_position']; ?></td>
                    <td><?php echo $credit['credit_heading']; ?></td>
                    <td><?php echo $credit['credit_title']; ?></td>
                    <td><?php echo $credit['credit_role']; ?></td>
                    <td><?php echo $credit['credit_director']; ?></td>
                </tr>
                <?php $oldvalue = $credit['category_title']; ?>
            <?php endif; ?>
       </table>
    <?php endif; ?>
<?php endforeach; ?>

解决方案

Move the table tags inside the IF statements

<?php foreach($credits as $credit) : ?>
    <?php if($credit['credit_type'] == "short") : ?>
      <table width="100%" cellpadding="0" cellspacing="0" border="0">
        <tr>
            <td><?php echo $credit['category_position']; ?></td>
            <td><?php echo $credit['category_title']; ?></td>
        </tr>
        <tr>
            <td><?php echo $credit['credit_heading']; ?></td>
            <td><a href="">Edit</a></td>
        </tr>
      </table>
    <?php endif; ?>
    <?php if($credit['credit_type'] == "long") : ?>
       <table width="100%" cellpadding="0" cellspacing="0" border="0">
        <tr>
            <td><?php echo $credit['category_position']; ?></td>
            <td><?php echo $credit['category_title']; ?></td>
            <td><strong>Title</strong></td>
            <td><strong>Role</strong></td>
            <td><strong>Director</strong></td>
        </tr>
        <tr>
            <td><?php echo $credit['credit_position']; ?></td>
            <td><?php echo $credit['credit_heading']; ?></td>
            <td><?php echo $credit['credit_title']; ?></td>
            <td><?php echo $credit['credit_role']; ?></td>
            <td><?php echo $credit['credit_director']; ?></td>
        </tr>
       </table>
    <?php endif; ?>
<?php endforeach; ?>

Note this is only going to work if you only ever have 2 credit_type values
