我将控制器中的数据传递给具有变量值的视图,但在我看来,我有两种形式,我想根据我拥有的变量数据显示表单。我尝试使用if(isset$_GET[])
方法,但它不起作用。以下是我的代码。请纠正我在哪里犯错误。
public function epacat($pa_cat_id)
{
$this->top();
$data['pa_cat'] = $this->adata->parentCategories();
//BELOW I AM PASSING DATA
$data['epa_cat'] = $this->adata->epacatQ($pa_cat_id);
$this->load->view('am/parent-categories/parent_categories',$data);
$this->bottom();
}
<div class="row">
//WANT TO DISPLAY IF I GOT VARIABLE
<?php if(isset(['epacat'])):?>
<div class="col-md-12">
<?php echo form_open('admin/apacat');?>
<label><h4>Update Parent Category</h4></label>
<?php echo form_input(['name'=>'pa_cat_name','class'=>'form-control','placeholder'=>'Enter your parent category','value'=>set_value('pa_cat_name',$pc->pa_cat_name)]);?>
<button type="reset" class="btn btn-warning">Reset</button> <button type="submit" class="btn btn-primary">Submit</button>
<?php form_close();?>
</div>
//WANT TO DISPLAY IF I NOT GOT VARIABLE
<?php else:?>
<div class="col-md-12">
<?php echo form_open('admin/apacat');?>
<label><h4>Add Parent Category</h4></label>
<?php echo form_input(['name'=>'pa_cat_name','class'=>'form-control','placeholder'=>'Enter your parent category','value'=>set_value('pa_cat_name')]);?>
<button type="reset" class="btn btn-warning">Reset</button> <button type="submit" class="btn btn-primary">Submit</button>
<?php form_close();?>
</div>
<?php endif;?>
</div>

您已在控制器中正确执行此操作
$data['epa_cat'] = $this->adata->epacatQ($pa_cat_id);
$this->load->view('am/parent-categories/parent_categories',$data);
在视图中,$data['epa_cat']
变为$epa_cat
。
例如,如果$epa_cat
是一个字符串,那么
<p><?php echo $epa_cat; ?></p>
或者,如果$epa_cat
是布尔值,您可以像这样检查
if ($epa_cat) {
// Do stuff
}

你可以这样写
public function epacat($pa_cat_id)
{
$this->top();
$data['pa_cat'] = $this->adata->parentCategories();
//BELOW I AM PASSING DATA
$data['epa_cat'] = $this->adata->epacatQ($pa_cat_id);
$this->load->view('am/parent-categories/parent_categories',$data);
$this->bottom();
}
<div class="row">
//WANT TO DISPLAY IF I GOT VARIABLE
<?php if($epacat):?>
<div class="col-md-12">
<?php echo form_open('admin/apacat');?>
<label><h4>Update Parent Category</h4></label>
<?php echo form_input(['name'=>'pa_cat_name','class'=>'form-control','placeholder'=>'Enter your parent category','value'=>set_value('pa_cat_name',$pa_cat->pa_cat_name)]);?>
<button type="reset" class="btn btn-warning">Reset</button> <button type="submit" class="btn btn-primary">Submit</button>
<?php form_close();?>
</div>
//WANT TO DISPLAY IF I NOT GOT VARIABLE
<?php else:?>
<div class="col-md-12">
<?php echo form_open('admin/apacat');?>
<label><h4>Add Parent Category</h4></label>
<?php echo form_input(['name'=>'pa_cat_name','class'=>'form-control','placeholder'=>'Enter your parent category','value'=>set_value('pa_cat_name')]);?>
<button type="reset" class="btn btn-warning">Reset</button> <button type="submit" class="btn btn-primary">Submit</button>
<?php form_close();?>
</div>
<?php endif;?>
</div>

只是为了好玩(而不是测试)
使用一个HTML块并根据$ epa_cat
派生不同的位<?php
if($epa_cat){
$label = 'Update';
$value = set_value('pa_cat_name', $pc->pa_cat_name);
} else {
$label = 'Add';
$value = set_value('pa_cat_name');
}
?>
<div class="row">
<div class="col-md-12">
<?= form_open('admin/apacat'); ?>
<label><h4><?=$label;?> Parent Category</h4></label>
<?= form_input(['name' => 'pa_cat_name', 'class' => 'form-control', 'placeholder' => 'Enter your parent category', 'value' => $value]); ?>
<button type="reset" class="btn btn-warning">Reset</button>
<button type="submit" class="btn btn-primary">Submit</button>
<?php form_close(); ?>
</div>
</div>
仍然不确定$pc->pa_cat_name
来自哪里,但是根据提供的内容,这将是第一次尝试。
我还将<?php echo
更改为<?=
作为可以使用的演示。
