PHP Mysql 作为参数 TextArea 超过 1 行

Question

我在将包含多行的文本区域传递到另一页时遇到问题。

我有 3 页：

1.-_testInsertText.php = 在数据库中插入新文本

2.-_testShowText.php = SELECT 数据库中的文本并重定向到修改页面

3.-_testTextModify.php = 更新 _testShowText.php

传递的文本

我的 table 来自数据库的结构：

CREATE TABLE `tblTest`
(
   `clmSerie`    int     (11) NOT NULL
  ,`clmTextArea` text         NOT NULL
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

如果我通过 _testInsertText.php 插入两行文本，我可以通过 _testShowText.php

正确显示

我的问题是将那些多于一行的记录重定向（通过 href）到 _testTextModify.php 页面（对于 1 行工作正常）。它不是重定向。

你能帮帮我吗？

我的代码可以在下面找到：

1.-_testInsertText.php

Answer 1

感谢 Sloan Thrasher 的评论，我修改了 _testTextModify.php 和 _testShowText.php 现在我将内容传递到一个隐藏的 TextArea 而不是一个 href 到修改页面，当它带有多行时它现在工作正常。

谢谢大家:)

新代码如下：

_testTextModify.php

<?php
    if(isset($_POST['fromTestShowText']))
    {
        $txtEvolucionOld = $_POST['descripcion'];
        $idSerie         = $_POST['serie'];
    }
    if(isset($_POST['Modify']) && isset($_POST["txtEvolucionOld"]))
    {
        $txtEvolucionOld = $_POST["txtEvolucionOld"];
        require_once('mysqli_connect.php');
        $query = "UPDATE  tblTest 
                  SET     clmTextArea  = ?
                  WHERE   clmSerie     = ?
                    ";
        $stmt = mysqli_prepare($dbc, $query);

        mysqli_stmt_bind_param($stmt, "ss", $_POST['txtEvolucionOld'], $_POST['idSerie']);
        mysqli_stmt_execute($stmt);
        $affected_rows = mysqli_stmt_affected_rows($stmt);
        echo "<br>". "affected_rows={"     . $affected_rows    ."}";
        if($affected_rows == 1)
        {
            $txtEvolucionOld = $recibeSerieEvolucion = '';
            echo "Modified";
            mysqli_stmt_close($stmt);
        }
        else
        {
            ini_set('display_errors', 'On');
            mysqli_stmt_close($stmt);
        }
    }
