如何在 foreach 循环 PHP 中创建和命名复选框

Question

I seem to be a little stuck with this.

I am trying to create checkboxes within a table of data within a foreach loop.

    foreach($datas as $data){
      echo "<tr>";
      echo "<td><input type='checkbox' name='counter[]'></input></td>";
      echo "<td>" .$data['employeeName']. "</td>";
      echo "<td>" .$data['amount']. "</td>";
      echo "<td>" .$data['reason']. "</td>";
    }

This will print out a table of employee reimbursements that have yet to be reimbursed. From here I am wanting to be able to have the user check the checkboxes in multiple rows, and run a SQL database UPDATE statement to update the date of reimbursement in the database.

I'm really confused on how I would name the checkboxes, and submit them to the following page. Thank you in advance for your help, and please let me know if you need any additional information!

Answer 1

You will have to give the employee id as the value of the checkbox

<form name="employee" method="POST">
        foreach($datas as $data)
        {
          echo "<tr>";
          echo "<td><input type='checkbox' name='counter[]' value=$data['id']></input></td>";
          echo "<td>" .$data['employeeName']. "</td>";
          echo "<td>" .$data['amount']. "</td>";
          echo "<td>" .$data['reason']. "</td>";
        }
<button type="submit"  value="Submit">Submit</button>
</form>

When You Submit the form you will get all employees id checked in the form.

$emloyee=$_POST['counter'];

You will get the data as array.

Then for each employeeid you can update the date of reimbursement.

Hope this helps.

You need to pass value of employee id in checkbox; so when you select checkbox and submit form, you will get all checked employee id's in post data. Here is complete code that may be useful for you to go through.

// On form post this code will be executed
if (isset($_POST['submit'])) {
    // this will give you all employee id which you have selected in array
    // it will be blank if you have not selected any employee
    $counter = isset($_POST['counter']) && !empty($_POST['counter']) ? $_POST['counter'] : [];

    // update statement here 
    if (!empty($counter)) {
        foreach ($counter as $key => $empId) {
            // update statement goes here
            // you can update statement based on $empId here
        }
    }   
}

// sample data; make sure you have employee id that you can use in update statement later on
$datas = [
    ['id' => 1, 'employeeName' => 'John', 'amount' => 100, 'reason' => 'reason 1'],
    ['id' => 2, 'employeeName' => 'Heily', 'amount' => 200, 'reason' => 'reason 2'],
    ['id' => 3, 'employeeName' => 'Keith', 'amount' => 150, 'reason' => 'reason 3']
];

// Your form
echo "<form method='post'>";
echo "<table>";
foreach($datas as $data){
    echo "<tr>";
    echo "<td><input type='checkbox' name='counter[]' value='".$data['id']."'></input></td>"; // added employee id as value here 
    echo "<td>" .$data['employeeName']. "</td>";
    echo "<td>" .$data['amount']. "</td>";
    echo "<td>" .$data['reason']. "</td>";
}
echo "</table>";
echo "<input type='submit' name='submit'>";
echo "<form>";
