Question

how would I do an if / else statement for such? the user has the option of adding images or not. if the add images, i want the if to run and if they dont I want the else to run because depending on whether or not the add an image they will have two different end.

if (isset($_POST['formsubmitted'])) { 

if (isset($_POST['name'])){  }else{  }

if (isset($_POST['state'])){  }else{  }

if (isset($_FILES['images']['name'])) { echo 'images'; exit;} else {echo 'no images'; exit;}


} #end main form submitted

if (isset($_FILES[‘images’][‘name’])) dosnt work because as of now even when no images are submitted it still says images submitted.

the html file fields are:

<form>
<input type='file' name='images[]' id=''>
<input type='file' name='images[]' id=''>
<input type='file' name='images[]' id=''>
<input type = "submit">    
</form>

Answer 1

You should try this

Submit.php

<pre>
<?php 
// those index are empty the array filter remove this 

echo "without filter"."<br>";
print_r($_FILES['images']['name']);

echo "filter"."<br>";
$usersFileUpload = array_filter($_FILES['images']['name']);
print_r($usersFileUpload);

$usersFileUploadCount = count($usersFileUpload);

for($i=0;$i<=$usersFileUploadCount;$i++){
    echo $usersFileUpload[$i]."<br>";

    // insert Table     
}
?>

HtmlForm.php

<form action="submit.php" method="post" enctype="multipart/form-data" name="images">
<input type='file' name='images[]' id=''><br />
<input type='file' name='images[]' id=''><br />
<input type='file' name='images[]' id=''>
<input name="" type="submit" />
</form>
