【问题描述】：

我的“if else”条件不起作用。

我想通过条件使“li”类激活或不激活，如果我的数据库表中包含 if else 语句中的单词的数据是正确的，那么“li”类将被激活。如果“if else”语句中的单词不在数据库中，那么“li”类将不会被激活。

在这种情况下，我从名为“pameran_belanda”的数据库表中获取“nama_kegiatan”列，以将值与“if else”条件匹配

这是我从表中获取数据的模型：

public function data()
{   
return $this->db->get("pameran_belanda")->result();

}

这是我的控制器：

 public function pameran_timeline()
    {
        $data['title'] = 'Belanda';
        $data['tes'] = $this->Info_pameran_belanda_model->data();
        $this->load->view('auth/header');
        $this->load->view('auth/sidebar',$data);
        $this->load->view('belanda/timelinev2',$data);
        $this->load->view('auth/footer');

    }

我的看法：

<ul>    

    <?php 
    foreach($tes as $ts){?>

    <li class="<?php echo strpos($ts->nama_kegiatan,'Pengalokasian Anggaran DIPA tahun 2020') == TRUE ? 'step step01 active' : 'step step01' ?>"><div class="step-inner">active1</div></li>
    <li class="<?php echo strpos($ts->nama_kegiatan,'Pembuatan Draft KAK & RAB untuk DIPA') == TRUE ? 'step step02 active' : 'step step02' ?>"><div class="step-inner">active2</div></li>
 <?php }?>





</ul>

无论我在条件下写什么字，输出都只显示“li”，类不活跃。

我的表结构有 4 个数据，我只制作了 2 个“li”来测试我的程序

id|keterangan|nama_gambar|nama_doc|           nama_kegiatan               |tanggal|
1 |tes       |tes        |tes     |Pengalokasian Anggaran DIPA tahun 2020 |2019-12-01|
2 |tes       |tes        |tes     |Pembuatan Draft KAK & RAB untuk DIPA   |2019-12-10|
3 | etc
4 | etc

【问题讨论】：

如果foreach($tes as $ts);，你的意思是在末尾有一个;，因为这意味着循环什么都不做
如果我用 foreach($tes as $ts) 替换：结果会打印很多“li”。根据我的情况，我只需要 2 个“里”。
确保 $data['tes'] 结果数组只返回两个？
否则分享您的完整视图页面编码
对于我的代码的完整结构，我将制作10个类“li”，表中的数据将只有10个。数据将根据用户输入增加，将在上传时填写形式。目前数据库中只有 4 个数据。对于原始结果，输出将是 4 个活动“li”类和 6 个活动“li”类。例如，我只想显示 10 个“li”类中的 2 个。错误在于给出 8 个“li”类的结果，根据我的代码应该只显示其中的 2 个。

标签： php html codeigniter web

【解决方案1】：

您需要以不同的方式使用foreach：

<ul>
<?php
    //$tes = array();
    function find($tes, $needle) {
        foreach($tes as $ts){
            if(strpos($ts->nama_kegiatan,$needle) !== false) {
                return true;
            }
        }
        return false;
    }
?>

        <li class="<?php echo find($tes, 'Pengalokasian Anggaran DIPA tahun 2020') !== false ? 'step step01 active' : 'step step01' ?>"><div class="step-inner">active1</div></li>
        <li class="<?php echo find($tes, 'Pembuatan Draft KAK & RAB untuk DIPA') !== false ? 'step step02 active' : 'step step02' ?>"><div class="step-inner">active2</div></li>
        <li>...</li>
</ul>

【讨论】：

感谢您的回答，但结果显示“li”处于非活动状态。 “li”类应该处于活动状态，因为数据库中已经存在“Pengalokasian Anggaran DIPA tahun 2020”和“Pembuatan Draft KAK & RAB untuk DIPA”
我从我的代码中删除了$tes = array();。你是复制了还是已经省略了？
当我删除“$tes = array();”出现错误显示 Message: Undefined property: mysqli_result::$nama_kegiatan
你是如何填充$tes数组的？
$tes 来自我的模型，用于从数据库中获取数据表。公共函数数据（） { 返回 $this->db->get("pameran_belanda")->result(); }
