 Posted: Mon Oct 31, 2011 8:30 am Post subject: truncate issue |
 |
|
Hello,
I'm having the following code :
| Code: | {section name=test loop=$obj->products}
{$obj->products[test].main|truncate:100}
{/section} |
What I want to do is to display the first 100 characters of each 'main' filed in the loop.
However it displays only 100 characters and then it leaves blank all the rest.
For example it displays:
main1: containing 30chars
main2: containing 50chars
main3: containing 20chars
main4:empty
main5: empty
and so on..
Any suggestions of how I can make this work?
Thanks in advance. |

Truncate does run for each iteration individually.
I assume the products array does not contain data. |

Hello,
The array contains data , the issue is that it seems that truncate is working only until it reaches the limitation of the 100 characters as a sum of characters.
In general saying I haven't seen this kind of problem again and I have used the 'truncate' function many times, that's way I'm desperate of working this out.
Thanks again,
P. |

test the original data too, it may not be truncate that is the problem.
| Code: | {section name=test loop=$obj->products}
orig: {$obj->products[test].main}
trunc: {$obj->products[test].main|truncate:100}
{/section} |

| Code: | {$foo = [
"hello world. I'm totally long and stuff. I need to be truncated at some point. Can you help me with that? is It possible, yes?",
"hello world. I'm totally long and stuff. I need to be truncated at some point. Can you help me with that? is It possible, yes?",
"hello world. I'm totally long and stuff. I need to be truncated at some point. Can you help me with that? is It possible, yes?",
"hello world. I'm totally long and stuff. I need to be truncated at some point. Can you help me with that? is It possible, yes?",
"hello world. I'm totally long and stuff. I need to be truncated at some point. Can you help me with that? is It possible, yes?",
"hello world. I'm totally long and stuff. I need to be truncated at some point. Can you help me with that? is It possible, yes?"
]}
{foreach $foo as $f}
{$f|truncate:50}<br />
{/foreach} |
prints | Code: | hello world. I'm totally long and stuff. I need...
hello world. I'm totally long and stuff. I need...
hello world. I'm totally long and stuff. I need...
hello world. I'm totally long and stuff. I need...
hello world. I'm totally long and stuff. I need...
hello world. I'm totally long and stuff. I need... |
