我想知道是否有人能夠幫助我請。父母和子女表唯一ID字段
我已經有一個形式,它允許用戶保存信息如下表:
父表
CREATE TABLE `finds` (
`userid` int(6) NOT NULL,
`locationid` int(6) NOT NULL,
`findid` int(6) NOT NULL auto_increment,
`findosgb36lat` float(10,6) NOT NULL,
`findosgb36lon` float(10,6) NOT NULL,
`dateoftrip` varchar(10) NOT NULL,
`findcategory` varchar(15) NOT NULL,
`findname` varchar(35) NOT NULL,
`finddescription` varchar(150) NOT NULL,
`detectorid` int(6) NOT NULL,
`searchheadid` int(6) NOT NULL,
`detectorsettings` varchar(600) default NULL,
`pasref` varchar(30) default NULL,
`findimage` varchar(200) default NULL,
`additionalcomments` varchar(600) default NULL,
`makepublic` varchar(3) NOT NULL default 'no',
PRIMARY KEY (`findid`),
KEY `userid` (`userid`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 AUTO_INCREMENT=1 ;
形式的部分將涉及圖像的保存地方的信息由用戶提供的將填充下表。
子表
CREATE TABLE `images` (
`imageid` int(6) NOT NULL auto_increment,
`userid` int(6) NOT NULL,
`locationid` int(6) NOT NULL,
`findid` int(6) NOT NULL,
`filepath` varchar(50) NOT NULL,
PRIMARY KEY (`imageid`),
KEY `findid` (`findid`)
) ENGINE=InnoDB
DEFAULT CHARSET=utf8 AUTO_INCREMENT=1 ;
其鏈接兩個是 'findid' 的字段。有人可以告訴我,有沒有辦法在父表中創建記錄,並因此分配唯一的「findid」值,同時將同一個唯一的「findid」值複製到子表中,以便可以鏈接記錄。
許多的感謝和親切的問候
表
<form enctype="multipart/form-data" action="add.php" method="POST">
Photo: <input type="file" name="photo"><br>
<input type="submit" value="Add">
</form>
保存PHP
<?php
//This is the directory where images will be saved
$target = "images2/";
$target = $target . basename($_FILES['photo']['name']);
//This gets all the other information from the form
$pic=($_FILES['photo']['name']);
// Connects to your Database
mysql_connect("host","user","password") or die(mysql_error()) ;
mysql_select_db("database") or die(mysql_error()) ;
//Writes the information to the database
mysql_query("INSERT INTO `test` VALUES ('$pic')") ;
//Writes the photo to the server
if(move_uploaded_file($_FILES['photo']['tmp_name'], $target))
{
//Tells you if its all ok
echo "The file ". basename($_FILES['uploadedfile']['name']). " has been uploaded, and your information has been added to the directory";
}
else {
//Gives and error if its not
echo "Sorry, there was a problem uploading your file.";
}
?>
嗨,非常感謝回覆我的帖子。我已經添加了圖像表單並將PHP腳本保存到了原始文章中,希望能夠提供更多關於我想要實現的信息。我遇到的問題是不保存文件,但我只是不確定,也許是因爲我是新手,如何在獨特的'findid'尚未創建時鏈接父記錄和子記錄父表。親切的問候 – IRHM
