Question

Parse the text file to extract its data and display that data in a table using Yii2 framework

Below is the javascript code used in my form:

$('#idOfButton').click(function(){
var id = $('#input').val(); 
    $.get('index.php?r=tbltime/get-file',{ id : id },function(data){
        var data = $.parseJSON(data);
        alert(data);
    });
});

This is the controller code for the view:

public function actionGetFile($id)
{
    $id = file_get_contents($id);
    echo Json::encode($id);

}

The structure of my table in the form view:

<table id="sampleTbl", class="table table-striped table-bordered">
    <thead>
        <tr id="myRow">
            <th>BIB</th>
            <th>Time Start</th>
            <th>Time End</th>
        </tr> 
    </thead>
    <tbody></tbody>
</table>

Content of the text file:

202#00:00:00.000000#00:02:13.045000
764#00:03:12.037300#00:04:12.123000
223#00:04:50.011000#00:05:12.045000

I'm looking to display the content of my text file into the table, however, the alert function to show the file content is not working. Can anyone provide assistance?

It seems that the file_get_contents function is unable to read your file because it is not located at C:\fakepath\dataimport.txt. If you wish to read a file from the D:/ disk, make sure to provide the full path to the file directory like this:

file_get_contents('FULL PATH TO THE FILE DIRECTORY'.$id)

. However, hardcoding values in your script may cause issues when moving the code to a server.

To access a file from the C:\ disk, you can simply copy the file from disk D:\ to C:\fakepath\dataimport.txt.

In your controller, after the line echo Json::encode($id);, add the line Yii::app()->end(); to prevent rendering any view files in that action.

Update

There are three possible scenarios:

First scenario: This scenario involves displaying a file that you are already aware of and have control over. Simply copy the file into your project folder and provide a relative path for the function to read. This method will work even when deploying the project on other servers.

Second scenario: If the file comes from an end user, you must first upload the file using PHP and then send the file content to your Ajax script.

Third scenario: You can use JavaScript to read the file's content and display it in the view. Check out this example:

When your alert appears, what is the response code of the AJAX GET request? If there are any errors, please include them here.

UPDATE: It seems that in the input where you are providing the file name, only the file name itself is present and not the full path to the file. To fix this issue, you need to adjust your action by adding the path prefix to the file_get_contents method:

public function actionGetFile($id)
{
    $fileContent = file_get_contents('D:/'.$id);
    echo Json::encode($fileContent);
    Yii::app()->end();
}
