Joomla wraps content in <p> tags

Question

I have Joomla 2.5 installed.
I developed some little module which generates html code.
Now, when it outputs the generated code, Joomla wraps it in <p> tags.
This causes two problems: 1. My css doesn't apply well because of paragraphing.
2. Paragraphs are crossing other tags.
For example here is a part of the module code:

<div class="formBlock">
    <div class="label"><?php echo LABEL_PROJ_DESC; ?></div>
    <textarea   class="descbox"
                id="descriptionBox"
                name="rp_proj_desc"
                cols="35" 
                rows="6"><?php echo $sender_description; ?></textarea>
</div>
<div class="formBlock">
    <div class="label"><?php echo LABEL_PRODUCTS; ?></div>
    <div class="formTable">
<?php                   
        foreach($products as $id => $product)
        {
            $checked = "";

            foreach($selectedProducts as $selectedId => $name)
            {
                if ($id == $selectedId)
                {
                    $checked = "yes";
                    break;
                }
            }
?>
        <div class="productsRow">
            <span>
                <input  class="formCheckbox"
                        type="checkbox" 
<?php 
                        if ($checked)
                        {
                            echo "checked=yes ";
                        }
?>
                        name="<?php echo PROD_PREFIX . $id; ?>" />
            </span>
            <span class="productsName"><?php echo trim($product); ?></span>
        </div>
<?php
        }
?>
    </div>
</div>

What I actually get is:

<div class="formBlock">
<div class="label">Your project description:</div>
<p>         <textarea   class="descbox"
                        id="descriptionBox"
                        name="rp_proj_desc"
                        cols="35" 
                        rows="6"></textarea>
        </div>
<div class="formBlock">
<div class="label">Our products you interested in:</div>
<div class="formTable">
<div class="productsRow">
                    <span></p>
<input  class="formCheckbox"
                                type="checkbox" 
                                name="product_0" />
                    </span>
                    <span class="productsName">Product1</span>
                </div>
<div class="productsRow">
                    <span></p>
<input  class="formCheckbox"
                                type="checkbox" 
                                name="product_1" />
                    </span>
                    <span class="productsName">Product2</span>
                </div>
<div class="productsRow">
                    <span></p>
<input  class="formCheckbox"
                                type="checkbox" 
                                name="product_2" />
                    </span>
                    <span class="productsName">Cheese</span>
                </div>
</p>
</div>
</div>

Put attention to <p> and </p> tags.
If search amount of <p> and </p> elements in "view source" page it will:
<p> - 12
</p> - 18

It means that something really wrong happening with Joomla...

System - Shortcodes

Any ideas?

Answer 1

Solved!!! It was System - Shortcodes plugin of Zauan Shortcodes which distroyed my code.

Answer 2

It's the editor (probably TinyMCE) that inserts these <p> tags. You should consider switching to "no editor" option (or another editor) - it can be set under "Global Configuration" screen, in the "Site" tab.
Also, in order to embed PHP code in your articles you should use a plugin such as DirectPHP.

Answer 3

Make sure that the textbox you created is not an RTF field. If you use RTF field, then

tags would be created automatically.
