php怎么修改表内字段内容
菜鸟求助 怎么在其他字段不变的情况下修改某个字段内容,我现在想修改'部门责任人审核:'这个字段里面的内容,但一直写不进去
while($row = mysql_fetch_assoc($query))
{
echo '日期:'.$row[time].' ';
echo '部门:'.$row[bumen].' ';
echo '姓名:'.$row[name].' ';
echo ' 职务:'.$row[zhiwu].'
';
echo '未打卡时间:'.$row[wdktime].'
';
echo '未打卡原因:'.$row[wdkyy].'
';
echo '部门责任人审核:'.$row[bmshtime].' ';
echo '人事行政部/总经理审批:'.$row[rsshtime].'
';
echo '';
echo '
';
}
echo '';
mysql_query('UPDATE wdksm SET
bmshtime = \'' . $_POST['test'] . '\'
WHERE time = \'' .$row[id] . '\'
');
?>
------解决思路----------------------
如果你想要mysql连接方式的话,可使用如下对你的源代码进行分析过后的代码:
<br />$query = mysql_query('SELECT * FROM wdksm ');<br />while($row = mysql_fetch_assoc($query))<br />{<br />$id=$row['id']; //要修改的id号没有被取得,应该在此处获取<br />echo '日期:'.$row["time"].' ';<br />echo '部门:'.$row["bumen"].' ';<br />echo '姓名:'.$row["name"].' ';<br />echo ' 职务:'.$row["zhiwu"].'<br />';<br />echo '未打卡时间:'.$row["wdktime"].'<br />';<br />echo '未打卡原因:'.$row["wdkyy"].'<br />';<br />echo '部门责任人审核:'.$row["bmshtime"].' ';<br />echo '人事行政部/总经理审批:'.$row["rsshtime"].'<br />';<br />//echo '<input name="" type="button" value="审核" onclick="" />'; //提交按钮放置在表单外,导致表单无法提交<br />echo '<hr /><br />'; <br />}<br />echo '<form name="bc" method="post" action=""> ';<br />echo '<input id="test" name="test" type="text" value="审核" />';<br />echo '<input type="submit" value="审核"/>'; //应在此处加上提交按钮,表单才能成功提交<br />echo '</form>';<br />/*mysql_query('UPDATE wdksm SET <br />bmshtime = \'' . $_POST['test'] . '\'<br />WHERE time = \'' .$row[id] . '\' //严重错误的sql语句 <br />');*/<br />//正确的sql语句<br />$sql='UPDATE wdksm SET <br />bmshtime = \'' . $_POST['test'] . '\'<br />WHERE id = \'' .$id . '\' <br />';<br />mysql_query($sql);<br /><br />
执行的结果是成功修改'部门责任人审核'.

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
