Unable to create image in magento api if product SKU contains slash(/) - magento

Question

I'm trying to create an image via magento image api by following the same code in this magento doc.
And its working fine except the SKU contains slash(/) character.
SKU: SPA-1XCHOC12/DS0
Here is the Error shows in httpd/error_log:
[Fri Feb 21 07:35:33 2014] [error] [client 8.35.201.40] PHP Fatal error: Uncaught SoapFault exception: [104] Cannot create image. in /var/www/html/product_api/image.php:22\nStack trace:\n#0 /var/www/html/product_api/image.php(22): SoapClient->__call('call', Array)\n#1 /var/www/html/product_api/image.php(22): SoapClient->call('67da4ad39466d6e...', 'product_media.c...', Array)\n#2 {main}\n thrown in /var/www/html/product_api/image.php on line 22
To identify the exact issue, i have added this code
$this->_fault('not_created', $e->getMessage()); in app/code/core/Mage/Catalog/Model/Product/Attribute/Media/Api.php
And this is the error:
[Fri Feb 21 07:41:56 2014] [error] [client 8.35.201.42] PHP Fatal error: Uncaught SoapFault exception: [104] Folder 'SPA-1XCHOC12' isn't writeable in /var/www/html/product_api/image.php:22\nStack trace:\n#0 /var/www/html/product_api/image.php(22): SoapClient->__call('call', Array)\n#1 /var/www/html/product_api/image.php(22): SoapClient->call('7f82eac2c509869...', 'product_media.c...', Array)\n#2 {main}\n thrown in /var/www/html/product_api/image.php on line 22
And media/catalog/product folder permission is 777. Still showing the same error.
Here is my Code:
Post Values are sku = 'SPA-1XCHOC12/DS0' and image_url='http://example.com/11233.jpg'
$sessionId = $proxy->login($api_user, $api_pwd);
$newImage = array(
'file' => array(
'name' => $_POST['sku'],
'content' => base64_encode(file_get_contents($_POST['img_url'])),
'mime' => 'image/jpeg'
),
'position' => 0,
'types' => array('small_image', 'image', 'thumbnail'),
'exclude' => 0
);
$imageFilename = $proxy->call($sessionId, 'product_media.create', array($_POST['sku'], $newImage));

Answer 1

Since your image is being generated by the sku, which you are sending to the routine manually, then why not clean it up there. It won't affect anything else.
Post Values are sku = 'SPA-1XCHOC12/DS0' and image_url='http://example.com/11233.jpg'
$sessionId = $proxy->login($api_user, $api_pwd);
// Replace slashes like waldek_c suggested
$sku_filename = str_replace("/","_",$_POST['sku']).".jpg";
$newImage = array(
'file' => array(
'name' => $sku_filename, // Put filtered $sku_filename var here from above
'content' => base64_encode(file_get_contents($_POST['img_url'])),
'mime' => 'image/jpeg'
),
'position' => 0,
'types' => array('small_image', 'image', 'thumbnail'),
'exclude' => 0
);
$imageFilename = $proxy->call($sessionId, 'product_media.create', array($_POST['sku'], $newImage));
The image filename will be SPA-1XCHOC12_DS0.jpg instead of SPA-1XCHOC12/DS0.
