Question

我想在Controller中获取post值，以便我像这样完成我的代码。控制器看起来像这样

public function save_expense($id = NULL)
{
   $data['amount'] = $this->input->post('amount',TRUE);
   var_dump($data['amount'] );
   print_r($data['amount']);
}

我的查看文件如下所示

 <form class="col s12"  enctype="multipart/form-data"  action="<?php echo base_url();?>admin/transactions/save_expense/<?php if (!empty($expense_info)) { echo $expense_info->transactions_id;}?>" method="post">
     <div class="row">
        <div class="input-field col s12">
                    <input placeholder="Amount"  type="text"  required name="amount" id="amount" value="<?php if (!empty($expense_info)) {echo $expense_info->amount;}?>">
                    <label for="amount"><?= lang('amount') ?></label>
        </div>
     </div>
    <div class="btn-area">
       <button class="btn waves-effect waves-light " type="submit" name="action">Update </button>
    </div>
 </form>

我的.htaccess文件看起来像这样

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteRule ^(application) - [F,L] 
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule .* index.php/$0 [PT,L]
</IfModule>

我没有得到任何传递给控制器的价值，请帮我解决我的问题

我测试了它并且工作正常。请参阅下面的代码并检查是否存在差异

HTML

<form class="col s12" enctype="multipart/form-data" action="<?php echo site_url();?>/extras/transactions/12333" method="post">
    <div class="row">
        <div class="input-field col s12">
            <input placeholder="Amount" type="text" required name="amount" id="amount">
        </div>
    </div>
    <div class="btn-area">
        <button class="btn waves-effect waves-light " type="submit" name="action">Update</button>
    </div>
</form>

PHP

  function transactions($id = NULL){
    echo "ID: ".$id;
    echo "<br>";
    echo "AMOUNT: ".$this->input->post('amount',TRUE);
  }
