keeping textarea content after a form submission

keeping textarea content after a form submission

I am trying to keep a textbox and textarea content in its field after a
form submission
text Box code:
<div class="response">
<span>
<input class="textbox" id="textbox1" name="textbox1" type="text"
value="<?php if(isset($_POST['textbox1'])) { echo htmlentities
($_POST['textbox1']); }?>" />
</span> </div>
text area code:
<div class="response">
<span>
<textarea class="textarea" id="textarea1"
name="textarea1" type="text"
value="<?php if(isset($_POST['textarea1'])) {
echo htmlentities ($_POST['textarea1']); }?>" >
</textarea>
</span>
</div>
textbox code is working fine, but I am not able to keep the text area
content.
