2级重复项目

Question

I have a page that displays an organizational tree however in level 2 there are repeated items. What I wanted to is to avoid the duplicates...

Here's the example display:

<ul id="org" style="display: none;">
<li>Brit School                        
    <ul>
        <li>Amy Winehouse
            <ul>
                <li>Carina Round</li>
            </ul>
        </li>
        <li>Adele Adkins
            <ul>
                <li>Kreayshawn K</li>
                <li>Leona Lewis</li>
            </ul>
        </li>
        <li>Adele Adkins
            <ul>
                <li>Kreayshawn K</li>
                <li>Leona Lewis</li>
            </ul>
        <li>Arctic Monkey
            <ul>
                <li>PJ Harvey</li>
            </ul>
        </li>
    </ul>

</li>

I wanted to omit the 2nd record Adele this is my example code in PHP

<ul id="org" style="display: none;">
<?php foreach ($lvl1 as $genesA) {?>
    <li>
        <?php echo $genesA->LevelFullName1?>
        <?php if($genesA->lvlMemF) {?>
        <ul>
        <?php if($genesA->lvlMemF) {?>
            <?php foreach ($lvl2 as $genesB) {?>
                <?php if($genesB->lvlMemS) {?>
                <li><?php echo $genesB->LevelFullName2 ?>
                <?php if($genesB->lvlMemS) {?>
                  <ul>
                    <?php if($genesB->lvlMemS) {?>
                        <?php foreach ($lvl3 as $genesC) {?>
                            <?php if($genesB->lvlMemS == $genesC->referrerLvl3) {?>
                                <li>
                                    <?php echo $genesC->LevelFullName3?>
                                </li>
                            <?php } ?>
                        <?php } ?>
                    <?php } ?>
                  </ul>
                  <?php } ?>
                </li>
                <?php } else { ?>

                <?php } ?>
            <?php } ?>
        <?php } ?>
        </ul>

        <?php }?>
    </li>
<?php } ?>

I'm not so sure if I am heading on the right track I just want a dirty fix that's all :)

Answer 1

that should do it:

<?php
$seen = array();
?>
<ul id="org" style="display: none;">
<?php foreach ($lvl1 as $genesA) {?>
    <li>
        <?php echo $genesA->LevelFullName1?>
        <?php if($genesA->lvlMemF) {?>
        <ul>
        <?php if($genesA->lvlMemF) {?>
            <?php foreach ($lvl2 as $genesB) {?>
                <?php if($genesB->lvlMemS) {?>
                <li><?php echo $genesB->LevelFullName2 ?>
                <?php if($genesB->lvlMemS) {?>
                  <ul>
                    <?php if($genesB->lvlMemS) {?>
                        <?php foreach ($lvl3 as $genesC) {?>
                            <?php if($genesB->lvlMemS == $genesC->referrerLvl3) {?>
                                <?php if(!in_array($genesC->LevelFullName3, $seen)?>
                                <li>
                                    <?php echo $genesC->LevelFullName3?>
                                    <?php $seen[] =$genesC->LevelFullName3;?>
                                </li>
                                <?php }?>
                            <?php } ?>
                        <?php } ?>
                    <?php } ?>
                  </ul>
                  <?php } ?>
                </li>
                <?php } else { ?>

                <?php } ?>
            <?php } ?>
        <?php } ?>
        </ul>

        <?php }?>
    </li>
</ul>

you might want to check if my if is at the right place there because it could be that you get empty ul blocks if all the names already were seen.
