如何将数据传递到文本字段 [英] How to pass the data into the text-fields

问题描述

我正在尝试编写用于解析上传的 .csv 文件的代码.我已经编写了以下代码.控制器以数组的形式生成 CSV 文件的行，我也尝试使用 print_r($buffer); 语句打印，我得到了预期的输出.虽然可以使用 echo $string; 打印字符串，但我无法在保存到数据库之前将它们传递给文本字段进行编辑.

站点控制器

公共函数 actionImport(){$buffer[] = array();if(isset($_POST['submitCSV'])){$filename=$_FILES['filename']['tmp_name'];$fp = fopen("$文件名","r");如果($ fp){$i = 0;while(($buffer[$i++] = fgetcsv($fp,1000,",")) !== false){}if(!feof($fp))echo "Echo: 意外的 fgets() 失败\n";}fclose($fp);未设置($_POST['submitCSV'])；}$this->render('index',array('buffer'=>$buffer));}

查看(index.php)

<?php echo CHtml::beginForm('site/import',$method='post',$htmlOptions =array('enctype'=>'multipart/form-data'));?><div class="row"><input type="hidden" name="MAX_FILE_SIZE" value="30000"/><input type="file" name="filename" value="file"><?phpecho CHtml::submitButton('Submit', array('name'=>'submitCSV'));foreach($buffer 作为 $line)foreach($line 作为 $string)echo CHtml::activeTextField($string,$htmlOptions = array('value'=>$string));?>
<?php echo CHtml::endForm();?>

解决方案

在您的控制器中，尝试以下操作:

公共函数 actionImport(){如果 (isset($_POST['submitCSV'])) {$filename = $_FILES['filename']['tmp_name'];$fp = fopen("$文件名", "r");如果($ fp){while(($buffer = fgetcsv($fp,1000,",")) !== false){}if(!feof($fp)) {echo "Echo: 意外的 fgets() 失败\n";}}fclose($fp);如果(计数($缓冲)){$this->render('index',array('buffer' => $buffer));}}}

在您看来:

<代码><p><?CHtml::activeTextField($line, array('class' => 'login_textbox', 'style' => 'width:100%', 'value' => $line));?></p><?Endforeach;?>

您将一组数据(由 CSV 行组成)传递给您的视图，然后该视图遍历该数组并为每个数据呈现一个文本字段.确保您启用了 short_tags.

I am trying to write the code for parsing the uploaded .csv file. I have written the following code. The controller generates the rows of the CSV file in the form of arrays which I have also tried to print with print_r($buffer); statement and I get the expected output. Though the strings can be printed using echo $string;, but I am not able to pass them to the text-fields for editing before saving to the database.

SiteController

public function actionImport()
{
    $buffer[] = array();
    if(isset($_POST['submitCSV'])){
        $filename=$_FILES['filename']['tmp_name'];
        $fp = fopen("$filename","r");
            if($fp){
                $i = 0;
                while(($buffer[$i++] = fgetcsv($fp,1000,",")) !== false)
                {}
                if(!feof($fp))
                    echo "Echo: Unexpected fgets() fail\n";
            }
            fclose($fp);
            unset($_POST['submitCSV']);
    }
    $this->render('index',array('buffer'=>$buffer));
}

View(index.php)

<div class="form">
<?php echo CHtml::beginForm('site/import',$method='post',$htmlOptions =array('enctype'=>'multipart/form-data')); ?>

    <div class="row">
        <input type="hidden" name="MAX_FILE_SIZE" value="30000" />
        <input type="file" name="filename" value="file">
        <?php
            echo CHtml::submitButton('Submit', array('name'=>'submitCSV'));
            foreach($buffer as $line)
                foreach($line as $string)
                    echo CHtml::activeTextField($string,$htmlOptions = array('value'=>$string));
        ?>
</div>
<?php echo CHtml::endForm(); ?>

解决方案

In your controller, try something like:

public function actionImport()
{
    if (isset($_POST['submitCSV'])) {
        $filename = $_FILES['filename']['tmp_name'];
        $fp = fopen("$filename", "r");
        if($fp) {
            while(($buffer = fgetcsv($fp,1000,",")) !== false)
            {
            }
            if(!feof($fp)) {
               echo "Echo: Unexpected fgets() fail\n";
            }
        }
        fclose($fp);
        if (count($buffer)) {
            $this->render('index',array('buffer' => $buffer));
        }
    }
}

And in your view:

<? foreach ($buffer as $line): ?>

   <p><? CHtml::activeTextField($line, array('class' => 'login_textbox', 'style' => 'width:100%', 'value' => $line)); ?> </p>

<? endforeach; ?>

You're passing an array of data (composed of your CSV lines) to your view, which is then iterating over the array and rendering a text field for each one. Make sure you have short_tags enabled.
