语法错误：意外的'。 在Codeigniter中？

Question

我有一个错误

类型：ParseError

消息：语法错误，意外的“。”

文件名：/opt/lampp/htdocs/cctv/application/views/edit_camera.php

我的错误在哪里？

<div style="margin-top: " class="form-group">
  <label>Terminal</label>
  <select class="form-control input-lg" id="required" name='id_terminal' data-placeholder="Pilih transaksi">
   <?php foreach ($get_camera as $cam) { 
     if ($cam->id_camera == $this->uri->segment(3)) {
       foreach ($terminal as $ter) { 
         if($ter->id_terminal == $cam->id_terminal) { ?>
           <?php echo "<option ".($cam->id_terminal == $ter->id_terminal ? ." selected='selected'".).">".$ter->nama_terminal."</option>" ?>
        <?php   }
       }
     } ?>
   <?php } ?>
  </select>
</div>

Answer 1

这条线

<?php echo "<option ".($cam->id_terminal == $ter->id_terminal ? ." selected='selected'".).">".$ter->nama_terminal."</option>" ?>

应该更改为

<?php echo "<option ".($cam->id_terminal == $ter->id_terminal ? " selected='selected'" : '').">".$ter->nama_terminal."</option>" ?>

您只是添加了太多“。” 进行字符串连接，并错过了三元运算符上的“：”。

Answer 2

您应该尝试这种方式，但是连接字符串的方式存在问题：

<div style="margin-top: " class="form-group">
    <label>Terminal</label>
    <select class="form-control input-lg" id="required" name='id_terminal' data-placeholder="Pilih transaksi">
    <?php 
        foreach ($get_camera as $cam) { 
            if ($cam->id_camera == $this->uri->segment(3)) {
                foreach ($terminal as $ter) { 
                    if($ter->id_terminal == $cam->id_terminal) {
                        echo "<option ".($cam->id_terminal == $ter->id_terminal ? " selected='selected'":'').">".$ter->nama_terminal."</option>";
                     }
                }
            } 
        } 
    ?>
    </select>
</div>
