Not found error

[cat250]

One more problem...  I'm sorry if I bother u.

 

I have:

echo "Image: ".$json['Poster'].""; and if image exist I get in return URL... but if there's no image get a error:

Notice: Undefined index: Poster in C:\xampp\htdocs\file.php on line 48

 

How can I show a message error for this?

 

Maybe I have too many questions but it's first time when I use PHP and don't understand too much.

Help is appreciated, again. Thanks!

 

I readed about if, else... still can't solved.

You can use an IF:

 

if ( isset ( $json['Poster'] ) ) {

    // do what you need here

} else {

    // set error here

}

[kicken]

if (!isset($json['Poster'])){
   //not found
}
else {
  //found
}

if (!isset($json['Poster'])){
   //not found
}
else {
  //found
}

 

Thanks, but isn't working.

 

Tried with this:

if (!isset($json['Poster'])){

echo "Hi.";

}

else {

echo "Bye.";

}

 

Get "Bye."

It's working as it should, you just have your messages flipped.

 

Change echo "Hi" with echo "Bye" and vice versa.

 

The 'else' part is what's supposed to happen IF json['Poster'] IS set.

 

To get a better understanding of this, instead of using "Hi and Bye" as your test messages, try this:

 

if (!isset($json['Poster'])){
   echo "Poster is NOT set!";
}
else {
  echo "Poster IS set!";
}

 

Hope that helps

Ok, now i get "Poster IS set!"... but that isn't true. This is what i wanted to say above.

 

I try to explain again: I have in mysql 2 entries, one with poster and one without.

Script return "Poster IS set!" in both cases.

You will have to post more code.  The answers you have been given are correct.  If for some reason they are not working for you, then there must be something else in the code causing it to break.

[cat250]

mysql_connect("localhost", "root", "") or die(mysql_error());

mysql_select_db("movies") or die(mysql_error());

$f = mysql_query("SELECT * FROM movies") or die(mysql_error());

while($inf = mysql_fetch_assoc($f)) {

$two= $inf['id'];

$link = "http://www.imdbapi.com/?i=$two";

$thr = file_get_contents($link);

$json = json_decode($thr,true);

echo "<img src='".$json['Poster']."' />";

Perhaps Poster is set, but is empty.

 

mysql_connect("localhost", "root", "") or die(mysql_error());
mysql_select_db("movies") or die(mysql_error());
$f = mysql_query("SELECT * FROM movies") or die(mysql_error());
while($inf = mysql_fetch_assoc($f)) {
$two= $inf['id'];
$link = "http://www.imdbapi.com/?i=$two";
$thr = file_get_contents($link);
$json = json_decode($thr,true);
if(!empty($json['Poster'])) { echo "<img src='".$json['Poster']."' />";  }
