PHP CRUD JSON file instead of a database like mysql


I'm in a bit of pickle, I received a request to create CRUD app to edit JSON object in an array and upload them. I did a bit of research and came across http://www.taffydb.com/ but it doesn't really fit my requirements.

EDIT: I also came across jtables, but it use mysql, similar to http://www.jeasyui.com/tutorial/app/crud.php but it also uses mysql. Is it possible to skip the database portion and write directly to the JSON file?

As this is a very small JSON file, having a database would seem excessive. I have multiple objects in the JSON array which an external app would read from.

What are the viable options I could go for? Ideally the app needs to Add/Edit/Delete from the browser contents to JSON file.

Currently I'm able to display the data accordingly in tables. My code looks like this:

PHP:

<?php
$getfile = file_get_contents('test.json');
$jsonfile = json_decode($getfile);
?>

HTML:

<table align="center">
<tr>
  <th>Title</th>
  <th>Background Image</th>
  <th>Video URL (Link to Video)</th>
  <th>Description of Video</th>
</tr>
  <?php
    foreach ($jsonfile->playlist as $obj) {
      echo '<tr><td>' . $obj->title . '</td>';
      echo '<td>' . $obj->title_bg . '</td>';
      echo '<td>' . $obj->link . '</td>';
      echo '<td>' . $obj->description . '</td></tr>';
    }
  ?>
</table>

JSON:

{
  "playlist": [
    {
      "title": "Test title",
      "title_bg": "link/to/image.png",
      "link": "https://www.google.com",
      "description": "This is a test JSON Object"
    }
  ]
}

The JSON file will have multiple objects in the playlist array


Solution

  • You can do it in this way:

    test.json

    {
        "playlist": [
            {
                "title": "Test title1222212321321321",
                "title_bg": "link\/to\/image.png",
                "link": "https:\/\/www.google.com",
                "description": "This is a test JSON Object"
            }, {
                "title": "sdfdasf",
                "title_bg": "adsfdas",
                "link": "fdasf",
                "description": "dasfdasf"
            }, {
                "title": "This is a title ",
                "title_bg": "This is a title bg",
                "link": "This is a link2",
                "description": "This is a description"
            }
        ]
    }
    

    index.php

    <?php
    $getfile = file_get_contents('test.json');
    $jsonfile = json_decode($getfile);
    ?>
    <a href="http://localhost/test/add.php">Add</a>
    <table align="center">
        <tr>
            <th>Title</th>
            <th>Background Image</th>
            <th>Video URL (Link to Video)</th>
            <th>Description of Video</th>
            <th></th>
        </tr>
        <tbody>
            <?php foreach ($jsonfile->playlist as $index => $obj): ?>
                <tr>
                    <td><?php echo $obj->title; ?></td>
                    <td><?php echo $obj->title_bg; ?></td>
                    <td><?php echo $obj->link; ?></td>
                    <td><?php echo $obj->description; ?></td>
                    <td>
                        <a href="http://localhost/test/edit.php?id=<?php echo $index; ?>">Edit</a>
                        <a href="http://localhost/test/delete.php?id=<?php echo $index; ?>">Delete</a>
                    </td>
                </tr>
            <?php endforeach; ?>
        </tbody>
    </table>

            $all["playlist"] = array_values($all["playlist"]);

        header("Location: http://localhost/test/index.php");
    }
    ?>
    

    To run the script you must specify in each of these files, a file path JSON. You have to also change the address of links to your environment.
