Question

我有一个查询结果。

    | id | name     |
    -----------------
    | 3  | candi    |
    | 4  | gedangan |
    | 11 | sidoarjo |

我的问题是如何将查询结果显示在单个输入字段中。

<input type="text" name="tags" id="" value="Candi, Gedangan, Sidoarjo" />

这是我的疑问。

<?php 
   $query = mysql_query("SELECT kecamatan.KECAMATAN_ID , kecamatan.KECAMATAN_NAMA
         FROM sumber_air a 
         JOIN sumber_air_kecamatan ON a.ID_SUMBER=sumber_air_kecamatan.ID_SUMBER
         JOIN kecamatan ON sumber_air_kecamatan.KECAMATAN_ID=kecamatan.KECAMATAN_ID
         WHERE a.ID_SUMBER = " . $_GET['id'] . "'
         GROUP BY kecamatan.KECAMATAN_ID");

while ($row = mysql_fetch_array($query)) {
     <input type=text name=tags value=<?=$row['KECAMATAN_NAMA'];?> />
}
?>

Answer 1

$value = "";
while ($row = mysql_fetch_array($query)) {
     $value .= $row['KECAMATAN_NAMA'].", ";
}

echo '<input type="text" name="tags" value="'.$value.'" />';

Answer 2

你可以这样做：

<?php 
    $query = mysql_query("SELECT kecamatan.KECAMATAN_ID , kecamatan.KECAMATAN_NAMA
       FROM sumber_air a 
       JOIN sumber_air_kecamatan ON a.ID_SUMBER=sumber_air_kecamatan.ID_SUMBER
       JOIN kecamatan ON sumber_air_kecamatan.KECAMATAN_ID=kecamatan.KECAMATAN_ID
       WHERE a.ID_SUMBER = " . $_GET['id'] . "'
       GROUP BY kecamatan.KECAMATAN_ID");

    $tags = '';

    //adds every "KECAMATAN_NAMA" to $tags, seperated by ", "
    while ($row = mysql_fetch_array($query)) {
        $tags .= $row['KECAMATAN_NAMA'] . ', ';
    }

    //rtim($tags, ', ') removes the last ", " from the tags
    echo '<input type="text" name="tags" value="' . rtrim($tags, ', ') . '"/>';
?>

Answer 3

$res = "";
while ($row = mysql_fetch_array($query)) {
    // Build up a string of results
    $res .= $row['KECAMATAN_NAMA']. ", ";
}

//Remove last comma
$res = rtrim($res, ', ');

//Echo result
echo '<input type="text" name="tags" value="'.$res.'" />';

Answer 4

您可以将所有值收集到一个数组中，然后将它们与implode

连接起来

$names_array = array();
while ($row = mysql_fetch_assoc($query)) {
    $names_array[] = htmlentities($row['KECAMATAN_NAMA']);
}
$names = implode(', ', $names_array);
echo "<input type='text' name='tags' value='$names'/>";

如何在输入字段中显示查询结果的多个值？
