我有一个data.txt文件,它使用PHP将textarea中的内容发布到HTML页面。
我希望文本区域将新行读取为<br>
元素,这样当我创建新行时,它们就不会在同一行上。
示例:
Hello
Hello
等于
HelloHello
但我希望它等于
Hello
Hello
我已经尝试过实施n2lbr
,但很难用我的系统实现,所以如果你打算建议请说明一下。
这是我的代码:
HTML:
<form method="POST" action="process.php" onsubmit='return validate ()' >
<textarea cols='60' rows='8' id="input1" type="text" name="myInputName" style="background:white;border:2px solid #dfdfdf;color:black;height:50px;"></textarea>
<input type="submit" name="submitButton" value="Post" style="width:60px;height:55px;background:white;color:black;border:2px solid #dfdfdf;" class="cbutton" />
</form>
<form method="POST" action="clear.php">
<input type="submit" name="Clear" value="Erase" style="width:265px;height:30px;background:white;color:black;border:2px solid #dfdfdf;margin-top:2px;" class="cbutton"/>
</form>
</div>
<p style="font-size:35px;text-align:center;font-family:Raleway;">To do List</p>
<div id="list2" style="">
<?php
$myfilename = "data.txt";
if (file_exists($myfilename)) {
echo file_get_contents($myfilename);
nl2br($myfilename);
}
?>
PHP(PROCESS.PHP):
<?php
// We will put the data into a file in the current directory called "data.txt"
// But first of all, we need to check if the user actually pushed submit
if (isset($_POST['submitButton'])) {
// The user clicked submit
// Put the contents of the text into the file
file_put_contents('./data.txt', $_POST['myInputName'] . '</br>', FILE_APPEND);
$str = $_POST["myInputName"] echo nl2br($str);
// ./data.txt: the text file in which the data will be stored
// $_POST['myInputName']: What the user put in the form field named "myInputName"
// FILE_APPEND: This tells the function to append to the file and not to overwrite it.
header('Location: index.php');
}
提前致谢!
这有很多麻烦。

您没有回显nl2br()
的结果,您只是回显文件的原始内容,然后调用nl2br()
并忽略它返回的内容。它应该是:
echo nl2br(file_get_contents($myfilename));

只需使用PHP的内置函数nl2br()
,就可以这样做:
<?php
$stringFromTextArea = "The Quick brown Fox\nStumble upon\nA Bag of Worms\n";
$stringWithBR = nl2br($stringFromTextArea);
echo $stringWithBR;
同样的功能仍然可以用于使用file_get_contents()
过筛的内容,如下所示:
<?php
$stringFromFile = file_get_contents($pathToFile);
$stringWithBR = nl2br($stringFromFile);
echo $stringWithBR;
