Hi everyone,

 

Before beginning I just wanted to say I've posted the full page code, as well as the custom class code at the end of this post - it's in its revised state after making the revisions described below.

 

I've been trying to solve a problem with a php form that has an error on submit. The error I've been getting is as follows:

 

Fatal error: Cannot use object of type MyResult as array in /Applications/MAMP/htdocs/newsite/admin/insertNewGarment.php on line 109

 

Line 109 refers to this line:

 

$values[$garment_id]['colour'] = $colours[$i];

 

Even though I'm getting this error, the form seems to function partially in that it inserts the information into my database table.

 

The part doesn't work and which I assume is related to the error is the following code:

 

// build array of garment_id/category_id pairs, garment_id/colour_id pairs, and garment_id/size_id pairs one for each category, colour and size

$values = array();
$i = 0;

foreach ($_POST['category'] as $categories); {
    $values[$garment_id]['category'] = $categories;
    $values[$garment_id]['colour'] =  $colours[$i];
    $values[$garment_id]['size'] = $sizes[$i];
    $i++;
    }

// insert garment_id/category_id, garment_id/color_id, and garment_id/size_id pairs into garment to category, garment to color, and garment to size lookup tables

        
$k = array_keys($values);
foreach( $k as $key ) {
    $cat_sql = "INSERT INTO garment_to_category (garment_id, category_id) VALUES ($key, {$values[$key][category]})";
    $colour_sql = "INSERT INTO garment_to_colour (garment_id, colour_id) VALUES ($key, {$values[$key][colour]})";
    $size_sql = "INSERT INTO garment_to_size (garment_id, size_id) VALUES ($key, {$values[$key][size]})";


    $result = $db->query($cat_sql);
    $result = $db->query($colour_sql);
    $result = $db->query($size_sql);
}

 

I've found out since that the variable $colour is an MyResult object, not an array and can't be used that way.

 

I tried modifying MyResult as follows:

 

In __contruct() I added code to extract results from SQL query and store

them in a variable:

 

while ($row = $r->fetch_array()) {
    $this->data[]=$row;
}
mysqli_data_seek($r,0);

 

Then I added another function in MyResult to lookup stored results:

 

function getItem($index) {
    return $this->data[$index][0];
}

 

Finally I modified the code to use the result:

 

$values[$garment_id]['colour'] = $colours->getItem($i);

 

The problem now is that when I retest, I get the following error:

 

Parse error: syntax error, unexpected T_WHILE in /Applications/MAMP/htdocs/newsite/admin/classes/database.php on line 69

 

Line 67 in the class file is this:

 

while ($row = $r->fetch_array()) {

 

Can someone tell me what might be happening?
