How to execute PDO in a variable PHP


while($row =$result->fetch())
{
$output .= '
<tr>
<td>' . $row["ID_personne"] . '</td>
<td>' . $row["Nom"] . '</td>
<td>' . $row["Prenom"] . '</td>
<td>' . $row["Telephone"] . '</td>
<td>' . $row["Mail"] . '</td>
<td>' . $row["Categorie"] . '</td>
<td>' . $row["Type"] . '</td>
'.$q2 = $db->prepare("SELECT * FROM entretiens WHERE ID_entretien=:id");
$q2->bindValue(":id",$row["Entretien"]);
$q2->execute();
$entretien=$q2->fetch().'

<td>'.$entretien["Date"].'</td>
<td width=250>
<a class="btn btn-primary" href="update_personnes.php?ID_personne='.$row["ID_personne"].'"><span class="glyphicon glyphicon-pencil"></span> Modifier</a>

<a class="btn btn-danger" href="delete_personnes.php?ID_personne='.$row["ID_personne"].'"><span class="glyphicon glyphicon-remove"></span> Supprimer</a>
</td>
</tr>';
}
$output .= '</table>';
echo $output;



I have always an Error: ( ! ) Catchable fatal error: Object of class PDOStatement could not be converted to string in C:.......... on line 61('.$q2 = $db->prepare("SELECT * FROM entretiens WHERE ID_entretien=:id");
$row["Entretien"] it's a foreign key





Wouldn't it be easier to just use a JOIN inside the original query and retrieve all data at once? It seems you'll issue lots of queries currently depending on the size of the original query.

JOIN





You'd do yourself a lot of favours by formatting your code and making it neater when you write it.

There was some syntax error in your code as $q2 is being concat with html string. Improved code should be:


$q2


while ($row = $result->fetch()) {
$output .= '
<tr>
<td>' . $row["ID_personne"] . '</td>
<td>' . $row["Nom"] . '</td>
<td>' . $row["Prenom"] . '</td>
<td>' . $row["Telephone"] . '</td>
<td>' . $row["Mail"] . '</td>
<td>' . $row["Categorie"] . '</td>
<td>' . $row["Type"] . '</td>';
$q2 = $db->prepare("SELECT * FROM entretiens WHERE ID_entretien=:id");
$q2->bindValue(":id", $row["Entretien"]);
$q2->execute();
$entretien = $q2->fetch();

$output .= '<td>' . $entretien["Date"] . '</td>
<td width=250>
<a class="btn btn-primary" href="update_personnes.php?ID_personne=' . $row["ID_personne"] . '"><span class="glyphicon glyphicon-pencil"></span> Modifier</a>

<a class="btn btn-danger" href="delete_personnes.php?ID_personne=' . $row["ID_personne"] . '"><span class="glyphicon glyphicon-remove"></span> Supprimer</a>
</td>
</tr>';
}
$output .= '</table>';
echo $output;

PHP contact form sending but not receiving emails

PHP contact form sending but not receiving emails I have created a contact form using PHP to send the data. The form seems to send fine as there are no errors and success message appears, however I am not receving the emails into the designated inbox. I am using PHPMailer as I originally tried just using the php 'mail' command which I now understand is a bit hit and miss. I cannot see why I would not be receving the emails so I would be very grateful for any help that could be given. I'm quite new to PHP so please be patient with me :) <?php use PHPMailerPHPMailerPHPMailer; use PHPMailerPHPMailerException; $msg = ""; if (isset($_POST['submit'])) { require 'phpmailer/src/Exception.php'; require 'phpmailer/src/PHPMailer.php'; require 'phpmailer/src/SMTP.php'; function sendemail ($to, $from, $body) { $mail = new PHPMailer(true); $mail->setFrom($from); $mail->addAddress($to); $ma...

Do graphics cards have individual ID by which single devices can be distinguished?

Do graphics cards have individual ID by which single devices can be distinguished? I have several graphics cards of the same manufacturer and same model and I want to distinguish them not only by the pcie socket they reside in but by some individual value I can read from the hardware. Is there such value and if so what would it be called and how could I access it? Right now I'm using modern nvidia cards (10xx series) and nvidia inspector.but I'd prefer if there was any value that was also applicable to amd. I have programming and scripting knowledge. I am running Windows 10 1 Answer 1 This is a powershell example to pull information from video cards. The DeviceID is supposed to be unique but only if the manufacturer supports Windows Display Driver Model (WDDM). (I copied this directly from docs.microsoft.com) $strComputer = "." $colItems = get-wmiobject -class "Win32_VideoC...
