【问题描述】：
我正在尝试将 ID 复制到中间表中。由于某种原因，它为每个人输入了两次数据。
function addPeople($tags){
include('connect.php');
if($con==false){
}else if ($con==true){
foreach($tags as $key){
$checkPerson="SELECT Name from person WHERE Name='".$key."';";
$insertPerson="INSERT INTO person (Name) VALUES ('$key')";
$resultCheckPerson=mysqli_query($con,$checkPerson) or die(mysqli_error($con));
if(mysqli_num_rows($resultCheckPerson)>0){
//Do not add to database
}elseif($con->query($insertPerson)=== TRUE){
}
}
}
}
function add($image,$pathy,$array,$optional=null){
include('connect.php');
if($con==false){
}else if ($con==true){
$insertImage="INSERT INTO image (path) VALUES ('$pathy')";
$checkImage="SELECT path from image WHERE path='".$pathy."';";
$resultCheckImage=mysqli_query($con,$checkImage) or die(mysqli_error($con));
if(mysqli_num_rows($resultCheckImage)>0){
}else if($con->query($insertImage) === TRUE){
}
foreach($array as $key){
$checkPerson="SELECT Name from person WHERE Name='".$key."';";
$insertPerson="INSERT INTO person (Name) VALUES ('$key')";
$resultCheckPerson=mysqli_query($con,$checkPerson) or die(mysqli_error($con));
if(mysqli_num_rows($resultCheckPerson)>0){
//Do not add to database
}else if($con->query($insertPerson) === TRUE){
}
}
}
}
function getImageID($path){
include('connect.php');
if($con==false){
}else if ($con==true){
$getID="SELECT image_ID from image WHERE path ='".$path."';";
$resultGetID=mysqli_query($con,$getID)or die(mysqli_error($con));
$idArray=mysqli_fetch_array($resultGetID);
return $idArray[0];
}
}
function getPersonID($name){
include('connect.php');
if($con==false){
}else if ($con==true){
$getName="SELECT person_ID FROM person WHERE Name ='".$name."';";
$resultGetName=mysqli_query($con,$getName)or die(mysqli_error($con));
$arrayName=mysqli_fetch_array($resultGetName);
return $arrayName[0];
}
}
function addMiddle($imageID,$personID){
include('connect.php');
if($con==false){
}else if ($con==true){
$addData="INSERT INTO image_person (image_ID,person_ID) VALUES ('$imageID','$personID')";
$resultAddData=mysqli_query($con,$addData) or die(mysqli_error($con));
if($con->query($addData) === TRUE){
}
}
}
function huntExtract($x){
foreach($x as $imageFile){
echo "image".$imageFile." start<br>";
$withoutExt = preg_replace('/\\.[^.\\s]{3,4}$/', '', $imageFile);
$path="img/".$withoutExt.".jpg";
$tagsArray=getTags($imageFile);
add($imageFile,$path,$tagsArray);
$imageID=getImageID($path);
$image_ID=$imageID[0];
foreach ($tagsArray as $key){
echo" person ".$key."<br>";
$person_ID=getPersonID($key);
echo "Their ID is ".$person_ID."<br>";
addMiddle($image_ID,$person_ID);
}
echo "image".$imageFile." end<br>";
}
}
//phase 1: get all files in dir into a list or array
$dir='img';
$folder=scandir($dir);
//sanatize the array, we don't want junk in our trunk
if(($key = array_search('.', $folder)) !== false) {
unset($folder[$key]);
unset ($key);
}
if(($key = array_search('..', $folder)) !== false) {
unset($folder[$key]);
unset ($key);
}
if(($key = array_search('Thumbs.db', $folder)) !== false) {
unset($folder[$key]);
}
huntExtract($folder);
?>
addMiddle() 函数应该获取图片 ID，然后在循环中获取每个 personID 并将其与图像 ID 一起复制到名为 image_person 的表中。
如您所见，每个人的数据都是重复的。
