Echo to an input values ​​of a session

  • 772

I am trying something like this

<input value="<?php echo $_SESSION[empleados][nombre]?>">

The session comes from a query entered in an array

Namely:

<?php
while ($f=mysqli_fetch_array($result)) {
$nombre=$f['nombre'];
$sueldo=$f['sueldo'];

} $datosnuevos=array('id'=>$_GET['id'],'Nombre'=>$nombre,'Sueldo'=>$sueldo);
array_push($arreglo,$datosnuevos);
$_SESSION['empleados']=$arreglo;
?>

For each of the elements in the session, print its name separated by commas between one and the other within the same input.

Namely:

<input value="pepito, juanito, Luis">

I think the way to do this is to include them in an array but can someone tell me how??

php

  1. Best Answer

    You can use the function implode()as simple as;

    $nombres = implode(',',$_SESSION['empleados']);
echo '<input value="' . $nombres . '">

    The function implode()returns a string containing the values ​​of the array.

    $string (optional): Text string with which we can divide each element of the array within the resulting string.

    $array (required): Array that we want to convert to a string.

    I edit my answer to add more content;

    They can use the following function to do a multi implode;

    function multi_implode($array, $glue) {
    $ret = '';

    foreach ($array as $item) {
        if (is_array($item)) {
            $ret .= multi_implode($item, $glue) . $glue;
        } else {
            $ret .= $item . $glue;
        }
    }

    $ret = substr($ret, 0, 0-strlen($glue));

    return $ret;
}
echo multi_implode($_SESSION['empleados'],',');

  2. I think what you're trying to get is something like this:

    <input value="pepito">
<input value="jaimito">
<input value="juanito">

    from a multidimensional array (ok, in session), which saves them. So what you have in session, inside 'employee', is something like this:

    [
    [
        'nombre' => 'Pepito',
        'salario' => 900,
    ],
    [
        'nombre' => 'Jaimito',
        'salario' => 950,
    ],
    [
        'nombre' => 'Juanito',
        'salario' => 1900,
    ],
];

    so, to get all employees:

    $arr_empleados = $_SESSION[ 'empleado' ];

    And to print the inputs you can do:

    foreach($arr_empleados as $empleado) {

    echo '<input value="' . $empleado[ 'nombre' ] . '">';
}

    Edited: responding to the clarifications in the question

    To get something like this:

    <input value="pepito, juanito, Luis">

    the process of printing values ​​only varies a little, that is, once you have the array with the employees: $arr_empleados, you do the following:

    //Cuenta elementos para no poner coma al final
$num = count($arr_empleados) - 1;

echo '<input value="'; //abre input y atributo value
foreach($arr_empleados as $key => $empleado) {

    echo $empleado['nombre'];

    if ($key < $num)
        echo ', ';
}
echo '">'; //cierra input y atributo value
