如何显示在php中使用数组选择多个下拉菜单？ [英] How to display select multiple drop down from using array in php?

问题描述

我想像父母一样下拉，孩子是指使用引导CSS的多级任务。
我尝试了下面这个，但是我得到了所有课程的名字，我想要像下面这样下载：

Linux
--Linux Basics p>

CSS
--CSS基础知识

以下是我的代码：

 < ul class =sub-menustyle =border-right：2px solid＃012340;> 
<？php foreach（$ outContentArrResults AS $ courseName => $ valArrMenu）{？> 
< li class =menu-item-has-children> 
< a href =＃><？php echo isset（$ valArrMenu [0]）？ $ valArrMenu [0]： ;? >< / A> 
 
< ul class =sub-menustyle =border-right：2px solid＃012340; border-left：2px solid＃012340;> 
 <？php for（$ i = 0; $ i< count（$ valArrMenu ['slug']）; $ i ++）{？> 
< li> 
< a href =<？php echo $ config ['LIVE_URL'];？>课程/<？php isset（$ valArrMenu ['slug'] [$ i]）？$ valArrMenu [ 'slug'] [$ i]：'';？>><？php echo isset（$ valArrMenu [$ i]）？ $ valArrMenu [$ i]于：？;>< / A> 
< / li> 
<？php}？> 
< / ul> 
< / li> 
<？php}？> 
< / ul> 
  

以下是我的数组值：

<$ p数组
（
[mainCourse] =>数组
（
[0] => linux
[slug] = >数组
（
[0] => linux
[1] => linux-basics
[2] =>第一步
[ 3] =>最后
[4] => sdd
[5] => css
[6] => css-basics
[7] => ; css-introduction
[8] => linux-sub
[9] => test-sub-linux
）

[1] => linux基础知识
[2] =>第一步
[3] =>最后
[4] => sdd
[5] => css
[6] => css基础知识
[7] => css介绍
[8] => linux sub
[9] => test sub sub linux
）

）
$ arrCourses = $ this-> objWsCoursesModel-> getMainMenuCourses（）;
// print_r（$ arrCourses）;
$ outResults = array（）;
for（$ i = 0; $ i< count（$ arrCourses）; $ i ++）{
$ courseName = isset（$ arrCourses [$ i] ['course_name']）？ $ arrCourses [$ i] ['course_name']：'';
$ outResults ['mainCourse'] [] = $ courseName;
$ outResults ['mainCourse'] ['slug'] [] = isset（$ arrCourses [$ i] ['course_slug_name']）？ $ arrCourses [$ i] ['course_slug_name']：'';

解决方案

数组，这将很难实现;）

试试这个数组：

  $ arrCourses = $ this-> objWsCoursesModel-> getMainMenuCourses（）; 
 $ outResults = array（）; 
 for（$ i = 0; $ i< count（$ arrCourses）; $ i ++）{
 $ courseName = isset（$ arrCourses [$ i] ['course_name']）？ $ arrCourses [$ i] ['course_name']：''; 
 $ outResults ['mainCourse'] [$ courseName] [] = isset（$ arrCourses [$ i] ['course_slug_name']）？ $ arrCourses [$ i] ['course_slug_name']：'';; 
} 
  

试试这段代码。这是一种粗糙的代码。我不确定任何语法错误，但我认为它会像这样工作：

 < ul> 
<？php foreach（$ outContentArrResults AS $ courseName => $ valArrMenu）{？> 
< li class =menu-item-has-children> 
< a href =＃><？php echo $ courseName？>< / a> 
 
<？php for（$ valArrMenu as $ row）{？> 
< li> 
< a href =<？php echo $ config ['LIVE_URL'];？>课程/<？php isset（$ valArrMenu ['slug'] [$ i]）？$ valArrMenu [ 'slug'] [$ i]：'';？>><？php echo isset（$ valArrMenu [$ i]）？ $ valArrMenu [$ i]于：？;>< / A> 
< / li> 
<？php}？> 
< / ul> 
< / li> 
<？php}？> 
< / ul> 
  

I want drop down like parent,child means multilevel tasking using bootstrap CSS. I tried the below one but I am getting all courses name in child.I want drop down like

Linux --Linux Basics

CSS --CSS Basics

Below is my code:

<ul class="sub-menu" style="border-right: 2px solid #012340;">
    <?php foreach($outContentArrResults AS $courseName=> $valArrMenu){ ?>
        <li class="menu-item-has-children">
          <a href="#"><?php echo isset($valArrMenu[0]) ? $valArrMenu[0]:'';?  ></a>

            <ul class="sub-menu" style="border-right: 2px solid #012340;border-left: 2px solid #012340;">
            <?php for($i=0; $i<count($valArrMenu['slug']); $i++){?>
                <li>
                   <a href="<?php echo $config['LIVE_URL'];?>courses/<?php isset($valArrMenu['slug'][$i]) ? $valArrMenu['slug'][$i]:'';?>"><?php echo isset($valArrMenu[$i]) ? $valArrMenu[$i]:'';?></a>
                </li>
            <?php } ?>
            </ul>
        </li>
    <?php } ?>
    </ul>

Below is my array Value:

         Array
      (
              [mainCourse] => Array
      (
        [0] => linux
        [slug] => Array
             (  
                [0] => linux
                [1] => linux-basics
                [2] => first-steps
                [3] => last
                [4] => sdd
                [5] => css
                [6] => css-basics
                [7] => css-introduction
                [8] => linux-sub
                [9] => test-sub-sub-linux
            )

        [1] => linux Basics
        [2] => first steps
        [3] => last
        [4] => sdd
        [5] => css
        [6] => css Basics
        [7] => css Introduction
        [8] => linux sub
        [9] => test sub sub linux
    )

)
$arrCourses = $this->objWsCoursesModel->getMainMenuCourses();
        //print_r($arrCourses);
        $outResults = array();
        for($i=0; $i<count($arrCourses); $i++){
            $courseName = isset($arrCourses[$i]['course_name']) ? $arrCourses[$i]['course_name'] : '';
            $outResults['mainCourse'][] = $courseName;
            $outResults['mainCourse']['slug'][] = isset($arrCourses[$i]['course_slug_name']) ? $arrCourses[$i]['course_slug_name'] : '';
        }

解决方案

You are making a very complex array which will be hard to implement ;)

Try this array :

$arrCourses = $this->objWsCoursesModel->getMainMenuCourses();
$outResults = array();
for($i=0; $i<count($arrCourses); $i++){
    $courseName = isset($arrCourses[$i]['course_name']) ?    $arrCourses[$i]['course_name'] : '';
    $outResults['mainCourse'][$courseName][] = isset($arrCourses[$i]['course_slug_name']) ? $arrCourses[$i]['course_slug_name'] : '';;
}

And try this code. This is kind of rough code. I am not sure any syntax error but I think it will work like this:

<ul>
<?php foreach($outContentArrResults AS $courseName=> $valArrMenu){ ?>
<li class="menu-item-has-children">
    <a href="#"><?php echo $courseName ?></a>
    <ul class="sub-menu" style="border-right: 2px solid #012340;border-left: 2px solid #012340;">
        <?php for($valArrMenu as $row){?>
        <li>
            <a href="<?php echo $config['LIVE_URL'];?>courses/<?php isset($valArrMenu['slug'][$i]) ? $valArrMenu['slug'][$i]:'';?>"><?php echo isset($valArrMenu[$i]) ? $valArrMenu[$i]:'';?></a>
        </li>
        <?php } ?>
    </ul>
</li>
<?php } ?>
</ul>
