set values for a <form> element #solved
Posted 06 June 2006 - 03:38 AM
i have a text box with a default value of null.
There is a particular button i have that once you press it, it populates a select menu with data from a database.
when a user selects a particular item in the select menu i wish to set the textbox value to "some string".
i can use the $_POST array superglobal to to retrevie the information i need, but how do i set it ?

For radio, checkbox, select fields you would have to use something to add 'checked="checked"', 'selected="selected"', and so on. It's harder.

Parse error: syntax error, unexpected T_VARIABLE in /var/www/html/php/news_adder.php on line 32
heres line 32
<input type="text" name="title" value="<?php$_POST['title_value'] ?>"/>
also why do you have a "=" sign before the "$" sign when i do that i get a syntax error.

<input type="text" name="title" value="<?php echo $_POST['title_value'] ?>"/>
<input type="text" name="title" value="<?= $_POST['title_value'] ?>"/>

can believe i didnt think of it.
Just curious tho is that the only way to do it? what is the recomended way? all the books i have simply retrive values from forms. the only ones where they set values are for select menus.
