Question

这是我的数据库：database

那两行rows

当我试图找到＆＃34; CEC＆＃34; in＆＃34; banca＆＃34;行，一切正常（用CEC banca显示我的行）。如果我试图找到＆＃34; cec＆＃34;或者＆＃34; Cec＆＃34;或＆＃34; ceC＆＃34; in＆＃34; banca＆＃34;排，没有结果，我不知道为什么！如果我提交确切的＆＃34; TEXT＆＃34;我不想要那个。

那是PHP代码：

$valueToSearch = $_POST['valueToSearch'];
// search in all table columns
// using concat mysql function
$query = "SELECT * FROM fachitate WHERE CONCAT (ID, data, furnizor, suma, banca, firma, observatii) LIKE '%".$valueToSearch."%'" ;
$search_result = filterTable($query);

// function to connect and execute the query

    function filterTable($query)
    {
        $connect = mysqli_connect("localhost", "root", "MYPASS", "facturi_db");
        $filter_Result = mysqli_query($connect, $query);
        return $filter_Result;
    }


echo "<table>
<tr>
<th>ID</th>
<th>Data</th>
<th>Furnizor</th>
<th>Suma</th>
<th>Banca</th>
<th>Firma</th>
<th>Observatii</th>
</tr>";
while($row = mysqli_fetch_array($search_result))
  {
    echo "<td><font color='#000000'>" . $row['ID'] . "</td>";
    echo "<td><font color='#000000'>" . $row['data'] . "</td>";
    echo "<td><font color='#000000'>" . $row['furnizor'] . "</td>";
    echo "<td><font color='#000000'>" . $row['suma'] . "</td>";
    echo "<td><font color='#000000'>" . $row['banca'] . "</td>";
    echo "<td><font color='#000000'>" . $row['firma'] . "</td>";
    echo "<td><font color='#000000'>" . $row['observatii'] . "</td>";

  echo "</tr>";
    }

形式：

    <form action="myfilter.php" method="post">
        <input type="text" name="valueToSearch" placeholder="Adauga nou filtru">
        <input type="submit" name="search" value="Filtreaza"><br><br>
     </form>

请帮忙！谢谢！

像这样更新你的选择：

$query = "SELECT * FROM fachitate WHERE LOWER(CONCAT(ID, data, furnizor, suma, banca, firma, observatii)) LIKE '%".strtolower($valueToSearch)."%'" ;

如果您将搜索关键字和搜索字词转换为小写，则案例会变得不敏感;）

不区分大小写但敏感
