好吧,我的脚本应该看起来像那样.我必须主要在PHP中进行操作.按钮添加应将数据保存到文件,显示应读取该文件并将其放入textarea,删除必须删除所选行,然后重置将重置所有内容.
<?PHP
$plik =fopen("data.dat","a+");
@fputs($plik,$_POST["name"]. " " . $_POST["sname"] . " " . $_POST["adres"] . " " . $_POST["number"] . "<br>" );
fclose($plik);
?>
<html>
<body>
<form action = "<?PHP $_PHP_SELF ?>" method = "POST">
Name: <input type = "text" name = "name" /><br>
Second Name: <input type = "text" name = "sname" /><br>
Adres: <input type = "text" name = "adres" /><br>
Number: <input type = "text" name = "number" /><br>
<input type = "submit" name="add" value="Add"/>
<input type = "button" name="show" value="Show"/>
<input type = "button" name="reset" value="Reset"/>
<input type = "button" name="delete" value="Delete"/><br>
<textarea id="lista" name="lista" rows="20" cols="40" style="overflow:scroll" readonly="" wrap="off"></textarea>
</form>
</body>
</html>
最佳答案
我认为这应该可以做到：
原文链接：https://www.f2er.com/html/530436.html<?PHP
if(isset($_POST['action'])) {
switch($_POST['action']) {
case('Add'): ... break;
case('Show'): ... break;
case('Reset'): ... break;
case('Delete'): ... break;
default: ...
}
}
?>
<html>
<body>
<form action = "<?PHP $_PHP_SELF ?>" method = "POST">
Name: <input type = "text" name = "name" /><br>
Second Name: <input type = "text" name = "sname" /><br>
Adres: <input type = "text" name = "adres" /><br>
Number: <input type = "text" name = "number" /><br>
<input type = "submit" name="action" value="Add"/>
<input type = "submit" name="action" value="Show"/>
<input type = "submit" name="action" value="Reset"/>
<input type = "submit" name="action" value="Delete"/><br>
<textarea id="lista" name="lista" rows="20" cols="40" style="overflow:scroll" readonly="" wrap="off"></textarea>
</form>
</body>
</html>
如您所见,我刚刚将操作按钮的类型更改为“提交”,并为所有按钮设置了相同的名称.然后在PHP中,只需测试是否设置了动作,然后选择要执行的正确动作即可.希望能帮助到你
