Mantis Bug Tracker - Forums

Hi, once again I am calling for your help ^_^

Please show me how to add date_modified from mantis_bug_history_table into view issue page as a new column.

I am trying to adjust filter_api.php, but I got failed. Could you please help me?

Thank you so much!

I am using Mantis version 1.1.8.

What's the purpose of this?
You will get more than one date_modified in bug_history_table for every issue.

Hi,

Thanks for your reply Atrol!

Indeed, I want to get the most current Status Modified Date by select the max (date_modified) of field_name 'Status 'in mantis_bug_history_table.
I adjusted filter_api.php (change select and join clause)and could get out the result (by var_dump the query result to test out). However, I cannot display Status Modified Date in view_all_bug_page.php correctly.

Here is the error:

It just show the defaut date Jan-01-70, not the date in database. In fact, I can get out the right date by my query.

These are what I adjusted in columns_api.php

#print column title for Status Modified Date- Hung Tran
function print_column_title_date_modified( $p_sort, $p_dir, $p_columns_target = COLUMNS_TARGET_VIEW_PAGE ) {

if ( $p_columns_target != COLUMNS_TARGET_CSV_PAGE ) {
echo '<td>';
print_view_bug_sort_link( lang_get( 'status_modified_date' ), 'date_modified', $p_sort, $p_dir, $p_columns_target );
print_sort_icon( $p_dir, $p_sort, 'date_modified' );
echo '</td>';
} else {
echo lang_get( 'status_modified_date' );
}
}

# --------------------
# $p_columns_target: see COLUMNS_TARGET_* in constant_inc.php

//status date modified- Hung Tran
function print_column_date_modified( $p_row, $p_columns_target = COLUMNS_TARGET_VIEW_PAGE ) {

$t_date_modified = date( config_get( 'short_date_format' ), $p_row['date_modified'] );
echo '<td class="center">';

echo $t_date_modified;

echo '</td>';
}

I recommend to start with a var_dump of $p_row['date_modified'] in your function print_column_date_modified

var_dump($p_row['date_modified']) = null

Since it gets null, it displays the default date Jan-01-70, even i can get the data. Here is my screen:

I don't have the time to guide you step by step thru debugging.

If var_dump($p_row['date_modified']) = null you have to ask yourself why it's null.
Where is the place where you think that you set the field, ...

var_dump($p_row['date_modified']) = null

because I was using aggregate function MAX($t_mantis_bug_history_table_name.date_modified). This makes the returned column name '' (empty) instead of
'date_modified'. Then I have to use a trick in print function to get data. I made it. Thank you atrol and cas!
