codeigniter

问题 I'm dynamically creating a table from a MySQL query. For some reason, the 'notes' field below is only returning the first word of the string, although when I test it with echo($notes) it shows up just fine. $status is similarly set, and also is fine. What am I missing? I assume it has something to do with prepopulating the text field with the value. I'm using codeigniter. $notes = empty($row["notes"]) ? "None" : $row["notes"]; echo($notes); echo(' <tr class="even"> <td class="status-icons">'.

问题 I've already got this line in my header.. <meta http-equiv="content-type" content="text/html; charset=utf-8"> I have an input form and when I enter a pound sign £ it's coming out with a strange character before it.

If I submit my form and then print_r the $_POST array I get: [field2_title] => £ Question I thought the issue might be with the code igniter $this->input->post(

问题 Based on the documentation, %s will be replaced by field name when setting error messages. If you include %s in your error string, it will be replaced with the "human" name you used for your field when you set your rules. Is there a way to have multiple %s in the string and define them differently? 回答1: This is the line in the form validation library that creates the error message: // Build the error message $message = sprintf($line, $this->_translate_fieldname($row['label']), $param); $line
