我有这个表格
<form method="post" action="process.php">
Name: <input type="text" name="name" value="">
<br />
English: <input type="text" name="english" value="">
<br />
French: <input type="text" name="french" value="">
<br />
<input type="submit" name="submit" value="Submit">
</form>
我们在process.php
上进行此查询$query = "
UPDATE
`translations_structure`
SET
`updated_on` = '".time()."',
`english` = '".utf8_encode($english)."',
`french` = '".utf8_encode($french)."'
WHERE
`id` = '".$id."'";
如果我编辑表格语言并添加更多语言,表单将动态修改为例如
<form method="post" action="process.php">
Name: <input type="text" name="name" value="">
<br />
English: <input type="text" name="english" value="">
<br />
French: <input type="text" name="french" value="">
<br />
Spanish: <input type="text" name="spanish" value="">
<br />
German: <input type="text" name="german" value="">
<br />
<input type="submit" name="submit" value="Submit">
</form>
我需要动态编辑查询
$query = "
UPDATE
`translations_structure`
SET
`updated_on` = '".time()."',
`english` = '".utf8_encode($english)."',
`french` = '".utf8_encode($french)."',
`spanish` = '".utf8_encode($spanish)."',
`german` = '".utf8_encode($german)."'
WHERE
`id` = '".$id."'";
我不明白的是我是如何在查询代码中动态制作的 *表单字段的名称与变量i POST的名称相同 *并且表中列的名称与POST的名称相同
`english` = '".utf8_encode($english)."',
`french` = '".utf8_encode($french)."',
`spanish` = '".utf8_encode($spanish)."',
`german` = '".utf8_encode($german)."',
`other_language` = '".utf8_encode($other_language)."',
`other_language2` = '".utf8_encode($other_language2)."'
上面我已经解释了我如何进行查询,但我无法理解如何编写变量
我知道我需要的东西有点困难,但也许有人明白我的需要
谢谢你
我先解释一下我想做什么:
我有一个名为“翻译”的表,我存储语言。例如:英语,法语,西班牙语等。
我使用表单来更新新值,问题是我想动态不要手动在每个php文件上插入此查询,因为语言表将增长或编辑,我想动态工作而不是编辑每个php文件。
变量名称与数据库中的字段名称相同
我设法为表格翻译上的名字制作一个数组
这是我迄今为止的动态 问题是我不知道如何在查询$ _POST ['english'],$ _POST ['french']等中插入变量
$db = new DB();
$query = $db->query("SELECT * FROM `translations_languages` ORDER BY `name` ASC");
while($row = $query->fetch_assoc()){
$values[] = "`{$row['name']}` = '{$row['name']}'";
}
$dynamic_result = "".strtolower(implode(",", $values))."";
$query = "
UPDATE
`translations_structure`
SET
`updated_on` = '".time()."',
$dynamic_result
WHERE
`id` = '".$id."'
";
echo "$query";
这就是查询看起来正常的方式
$query = "
UPDATE
`translations_structure`
SET
`updated_on` = '".time()."',
`english` = '".utf8_encode($english)."',
`french` = '".utf8_encode($french)."',
`spanish` = '".utf8_encode($spanish)."'
WHERE
`id` = '".$id."'";
我想在查询中添加此值
`english` = '".utf8_encode($english)."',
`french` = '".utf8_encode($french)."',
`spanish` = '".utf8_encode($spanish)."'
答案 0 :(得分:0)
您只需要创建一个动态更新数组。像这样:
$languagesToUpdate = array();
// this is an example, you should modify as your script:
// create a variable/constant to make sure you update only allowed fields
$allowedLanguages = array('english' => true, 'french' => true, 'spanish' => true, 'german' => true, 'other_language' => true);
// iterate threw post and check for allowed languages and add to languagesToUpdate the language we need to update with it's value
foreach ($_POST as $post => $value) {
if (isset($allowedLanguages[$post]) && $allowedLanguages[$post]) {
$languagesToUpdate[] = '`' . $post . '` = "' . utf8_encode($value) . '"';
}
}
// add additional data like updated_on
$languagesToUpdate[] = '`updated_on` = ' . time() . '';
//update database
$db = 'UPDATE `translations_structure` SET '.implode(', ', $languagesToUpdate).' WHERE `id` = '.(int)$id;
// this will produce something like this:
// UPDATE `translations_structure` SET `english` = "English text", `spanish` = "Spanish text", `updated_on` = 1479720637 WHERE `id` = 1
