我有一张桌子“候选人”。当我想显示所选项目时，我收到了此消息

这是应该在datatble中显示结果的页面

<?php
require_once '../Model/Connexion.php';
$fonc = $_POST['fonc'];
$nex = $_POST['nex'];
$dispo = $_POST['dispo'];
$tech = $_POST['tech'];
$c = new Connexion();
$c->query("select nom_complet,fonction,email,nbre_exp,dispo,tech from candidat "
        . "where fonction = :fonc and nbre_exp = :nexp and dispo = :dispo and tech = :tech");
$c->bind(':fonc', '$fonc');//pour éviter l'injection SQL
$c->bind(':nexp', '$nex');//pour éviter l'injection SQL
$c->bind(':dispo', '$dispo');//pour éviter l'injection SQL
$c->bind(':tech', '$tech');//pour éviter l'injection SQL

我想在表单中进行搜索并将结果显示在另一页中。

答案 0 :(得分：1)

你这样做：

$c->query("SELECT nom_complet, fonction, email, nbre_exp,dispo,tech "
        . "FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME="."'candidat'");

我的猜测是表INFORMATION_SCHEMA.COLUMNS不包含名为nom_complet的列。

答案 1 :(得分：1)

请参阅有关INFORMATION_SCHEMA COLUMNS Table。

的MySQL文档

尝试使用这样的SQL： SELECT * FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME='candidat' AND COLUMN_NAME IN ('nom_complet', 'fonction', 'email', 'nbre_exp', 'dispo', 'tech');

然后使用$cl = $c->resultset();

然后使用foreach从您需要的$cl获取所有数据，并将其显示在您的网页上。
