Question

I want insert some articles. I want make a judge first, if the image value has already in the database, insert a null value.
For more explain:
If there have these data:

title1，image1
title2，image2 //this is image2 first appear, so insert it 
title3，image2 //image2 has already in the database, so insert an empty value for just image field
title4
title5，image3  

the final data insert into the database should like this:

 title | image
title1，image1
title2，image2 
title3
title4
title5，image3 

Here is my code, but it still insert the repeat value into the database. So is there any one can help me? thanks.

foreach{//first here has a foreach to make all the articles as a queue 
...   
if(!empty($image)){ //first judge if the insert article had a image value
$query1 = mysql_query("select * from articles where .image = '".$image."' ");
while ($row = mysql_fetch_array($query1)) {
$image1 = $row['image'];
}
}
if(!empty($image1)){ //make a query first if the image has already in the database
  mysql_query("INSERT INTO articles (title,image) SELECT '".$title."','' ");
}else{
  mysql_query("INSERT INTO articles (title,image) SELECT '".$title."','".$image."' ");;
}
}

Your first query contains an error. You have to remove the dot before “image”:

where **.**image
