# Images helper

The `images_helper.php` file provides helper functions to handle image paths efficiently. These functions ensure that images are correctly resized and assigned default values when necessary.

***

#### `addSizeToPath()`

**Purpose:**

This function appends a given size string before the file extension in an image path. It is useful for handling different image resolutions without modifying the original filenames.

**Parameters:**

* **`$path`** (string) – The original image file path.
* **`$size`** (string) – The size to be appended before the file extension (e.g., "150x150").

**Usage:**

```php
$imagePath = "/uploads/images/sample.jpg";
$resizedPath = addSizeToPath($imagePath, "150x150");

echo $resizedPath; 
// Output: "/uploads/images/sample_150x150.jpg"
```

`img_square()`

**Purpose:**

This function generates a square image URL (150x150) if the input contains a valid path. If no path is provided, it returns a default placeholder image.

**Parameters:**

* **`$item`** (array/object) – An object or array containing:
  * **`path`** (string) – The original image path.
  * **`resize`** (string, optional) – The resize option indicating a required transformation.

**Usage:**

```php
$item = ['path' => '/uploads/images/sample.jpg', 'resize' => '150x150'];

echo img_square($item); 
// Output: "/uploads/images/sample_150x150.jpg"
```

If the input does not contain a valid path:

```php
$item = ['path' => '', 'resize' => ''];
echo img_square($item);
// Output: "/uploads/assets/150x150.webp"
```

***

## `img_vertical()`

**Purpose:**

Similar to `img_square`, this function generates a vertically resized image URL (333x500). If no valid image is found, it returns a default placeholder image.

**Parameters:**

* **`$item`** (array/object) – An object or array containing:
  * **`path`** (string) – The original image path.
  * **`resize`** (string, optional) – The resize option indicating a required transformation.

**Usage:**

```php
$item = (object) ['path' => '/uploads/images/sample.jpg', 'resize' => '333x500'];
echo img_vertical($item); 
// Output: "/uploads/images/sample_333x500.jpg"
```

If the input does not contain a valid path:

```php
$item = ['path' => '', 'resize' => ''];
echo img_vertical($item);
// Output: "/uploads/assets/333x500.webp" 
```

**Conclusion**

The `images_helper.php` file provides essential functions for managing image paths dynamically, ensuring that resized images are correctly referenced while providing fallback images when needed.
