如何添加具有多个 php 值的 href link？

Question

我对添加 link 的 php Web 表单没有什么问题。

我希望表单将值记录在：

<a href="$_POST['field1']" target="_blank" rel="nofollow" title=".$_POST['field3']">.$_POST['field2']</a>

但我不知道该怎么做才能正常工作。

我的代码是... HTML 表单代码：

    <form action="myprocessingscript.php" method="POST">
        <p>Уеб Сайт: </p><input name="field1" type="text" placeholder="https://www.tvoiasait.com/" /><br />
        <p>Ключова дума: </p><input name="field2" type="text" placeholder="Моят Личен Блог" /><br />
        <p>Описание: </p><input name="field3" type="text" placeholder="Личен Блог за интересни неща" /><br />
        <br /><input type="submit" name="submit" value="Добави сайта">
    </form>

myprocessingscript.php代码为：

<?php
if(isset($_POST['field1']) && isset($_POST['field2']) && isset($_POST['field3'])) {
    $data = '<a href='.$_POST["field1"]' target='_blank' rel='nofollow' title='.$_POST["field3"]'>.$_POST["field2"]</a>' . "\n";
    $ret = file_put_contents('mydata.txt', $data, FILE_APPEND | LOCK_EX);
    if($ret === false) {
        die('There was an error writing this file');
    }
    else {
        echo "$ret bytes written to file";
    }
}
else {
   die('no post data to process');
}
?>

我的显示表单记录代码是：

   <?php
    $myfile = fopen("mydata.txt", "r") or die("Unable to open file!");
    while(!feof($myfile)) {
    echo fgets($myfile);
    }
    fclose($myfile);
    ?>

我想在我的网站上使用此表格，以便访问者可以将他们的 link 添加到其中。我不明白如何在 HTML 行中使用 $_POST['field1']。

感谢您的时间和关注。

This below "" string addition could solve your problem.

            $data = '<a href="'.$_POST["field1"].'" target="_blank" rel="nofollow" title="'.$_POST["field3"].'">'.$_POST["field2"].'</a>' . "\n";
            $ret = file_put_contents('mydata.txt', $data, FILE_APPEND | LOCK_EX);
            if($ret === false) {
                die('There was an error writing this file');
            } else {
                echo "$ret bytes written to file";
            }
        }
        else {
           die('no post data to process');
        }
    ?>

Answer 2

<a href="<?php echo $_POST['field1']?>" target="_blank" rel="nofollow" title="<?php echo $_POST['field3'] ?>"><?php echo $_POST['field2'] ?></a>

或

<?php

echo '<a href="' . $_POST['field1'] . '" target="_blank" rel="nofollow" 
title="' . $_POST['field3'] . '"><' . $_POST['field2'] . '</a>':

?>
