Question

我有几个xml文件。我试图将从这些xml文件收集的数据插入到数据库中。问题是一些插入而另一些则不插入。这是两个xml文件。插入的第一个没有任何pb，但是第二个没有插入数据库。

现在，这是我在php5中的代码：

<?php $link = mysql_connect('localhost', 'root', 'recipe'); if (!$link) { die('Could not connect: ' . mysql_error()); } mysql_select_db('php_database'); $sql = 'DROP TABLE IF EXISTS `recipe`'; mysql_query( $sql, $link ); $sql = 'CREATE TABLE `recipe` ( `idRecipe` TINYINT( 12) UNSIGNED NOT NULL AUTO_INCREMENT , `RecipeTitle` VARCHAR( 75 ) NOT NULL, `Yield` TINYINT( 5) UNSIGNED NOT NULL , `Steps` Text( 10000 ) NOT NULL, PRIMARY KEY ( `idRecipe` ) )'; echo 'Creating table: \'recipe\'....'; mysql_query( $sql, $link ); if ($handle = opendir('C:\wamp\www\PhP\Folder xml')) { while (false !== ($file = readdir($handle))) { //$i++; if ($file != '.' && $file != '..') { if (file_exists($file)) { $use_errors = libxml_use_internal_errors(true); $xml = simplexml_load_file($file); if (!$xml) { echo ("Cannot open the XML file $file "); } else { echo " "; $title=$xml->recipe->head->title; $yield=$xml->recipe->head->yield; $step=$xml->recipe->directions->step; echo "value of Recipe Title= $title, yield= $yield and step= $step"; mysql_query("INSERT INTO recipe (RecipeTitle,Yield,Steps) values ('$title', '$yield','$step')"); printf("Last inserted record has id %d\n", mysql_insert_id()); mysql_close($link); echo " "; $xmla= "$file"; $xmlDoc = new DOMDocument(); $xmlDoc->load($xmla); $cat = $xmlDoc->getElementsByTagName("cat"); $numOfcat = $cat->length; echo "@@ here is the number of cat :$numOfcat @@ "; $qty = $xmlDoc->getElementsByTagName("qty"); $numOfqty = $qty->length; echo "@@ here is the number of qty :$numOfqty @@ "; echo $xml->getName() . " "; // displays recipeml foreach($xml->children() as $child) { echo $child->getName() . ": " . $child . " "; //displays recipe: //echo "INSERT " . $child . " INTO...."; echo ("title= "); echo $xml->recipe->head->title . " ,\r\n" ; //displays the title echo ("category= "); echo $xml->recipe->head->categories->cat .

有什么建议吗？其中许多文件形式不好，但我使用Altova来检查这两个xml文件是否格式正确，并且altova确认它们都是格式良好的。我将不胜感激任何建议。

谢谢，

Answer 1

你有一个'在你的第二个方向 - ＆gt;步骤，这将使查询失败，因为'将被视为常规SQL之后的其余文本 - 它不是。

在将字符串插入查询之前，您应该对字符串使用mysql_real_escape_string。

或切换到MySQLi或使用预准备语句的DB抽象层。

Answer 2

mysql_real_escape_string（）将逃避您的数据＆amp;使用或死亡将报告失败的地方。基本调试......

$query="INSERT INTO recipe (RecipeTitle,Yield,Steps) values
                        ('".mysql_real_escape_string($title)."',
                         '".mysql_real_escape_string($yield)."',
                         '".mysql_real_escape_string($step)."')";
mysql_query($query,$link) or die(mysql_error());

在第一次迭代后关闭连接，然后再次建立链接。

通常不使用mysql_close（）必要的，作为非持久的开放链接自动关闭脚本执行结束。

不相关但使用网址友好路径，下划线而不是空格

$handle = opendir('C:\wamp\www\PhP\Folder_xml');
