validation and input field has text

[eluser]Mitja B.[/eluser]
I have small problem and i do not know if this is possible.

i validate with CI validation. Everything ok and works, but fileds that are not required are not validate. After page is refresh validate fields still havse text in it other fields are empty. Is it possible that even this fields have text even they are not validate.

Redna: &lt;input type="text" name="price_eur" value="&lt;?= $row-&gt;price_eur?&gt;" /><br>
SiMobil: &lt;input type="text" name="price_eur_simobil" /&gt;

SiMobil field lost text after validating.

Thx, hope undesrtand me
